Takeaways

• 💪 Resistance training is crucial for optimal health and longevity, with studies showing it can reduce the risk of all-cause mortality by 15%.
• 🏋️ Combining resistance training with cardio can further decrease the risk of all-cause mortality by an additional 14%, and also has benefits against diseases like cancer and diabetes.
• 🕒 The minimum effective dose of weight lifting for health benefits is just 30 to 60 minutes per week, which can be achieved during a lunch break or any free time.
• 🚀 For those with a busy lifestyle, even a short workout can yield significant health benefits, and it's not necessary to dedicate hours each day to the gym.
• 🏋️‍♂️ The mindset matters; some people aim to maximize gains, while others aim for just enough to get health benefits, and the approach to training should align with this mindset.
• 🔢 The current fitness community recommends 10 sets per muscle group per week for maximizing gains, but doing five or fewer sets can still provide nearly 70% of the results.
• 📉 There's a diminishing return on training volume; doing more sets doesn't proportionally increase gains, and can sometimes even be counterproductive.
• 📈 To maximize efficiency, focus on basic exercises like squats, bench press, and deadlifts, which are proven to be effective and don't require complex training techniques.
• ⏱️ Keep track of your progress by increasing loads week by week to ensure continuous stimulus for muscle growth, which is essential for making progress.
• 🤝 Be mindful of socializing in the gym; if time is limited, focus on the workout rather than spending time on social interactions or browsing social media.
• 🔄 Techniques like supersets, drop sets, and post sets can help increase the volume of a workout without extending the time spent in the gym, making workouts more efficient.

Q & A

What are the health benefits of resistance training according to the 2021 systematic review and meta-analysis?

The 2021 systematic review and meta-analysis of over 200,000 people concluded that muscle strengthening activities were associated with a 15% lower risk of all-cause mortality. Furthermore, combining resistance training with cardio was associated with an additional 14% lower risk of all-cause mortality.

How much time is recommended per week for resistance training to gain health benefits and build muscles?

The script suggests that just 30 to 60 minutes per week of resistance training can be sufficient for health benefits and muscle building, which can be done during a lunch break or any free time.

What is the current mindset in the fitness community regarding the relationship between the amount of exercise and gains?

The current mindset in the fitness community is that more exercise leads to more gains. However, the script points out that this is not the case due to diminishing returns and that doing the minimum can still yield significant results.

What is the 'minimum effective dose' for resistance training according to the meta-analysis mentioned in the script?

The meta-analysis analyzed 15 studies and found that on average, doing 10 sets per muscle group per week yielded the maximum results. However, doing five or fewer sets still provided almost 70% of the results.

What are some practical tips for making workouts more efficient and quicker?

The script suggests cutting the warm-up time, doing more supersets, performing drop sets, and incorporating post sets. It also emphasizes the importance of training close to failure and doing the eccentric part of the lift slowly to increase efficiency.

How does the script define 'failure' in the context of resistance training?

In the script, 'failure' is defined as the point where one can no longer perform another repetition with proper form. It is mentioned that people often underestimate failure by up to five reps.

What is the recommended approach to warming up before resistance training according to the script?

The script recommends warming up the specific muscle group being trained that day with light weight or bodyweight exercises for about 20 reps before moving on to the working weight, instead of a long general warm-up.

What is the role of supersets in reducing workout time?

Supersets involve working two different muscle groups back-to-back with little to no rest in between, allowing one to work both groups in the time it would normally take to work one, thus reducing overall workout time.

How can drop sets help in increasing the volume of a workout without doing more sets?

Drop sets involve performing a set to failure, then immediately reducing the weight by 20-30% and performing another set to failure, and repeating this process. This allows for an increased volume of work without the need for additional sets.

What is the difference between drop sets and post sets mentioned in the script?

Drop sets involve reducing the weight after a set to failure, while post sets involve performing multiple sets of the same weight with minimal rest in between, aiming to complete a high total number of repetitions.

How often should one train to maintain muscles according to the 2007 study mentioned in the script?

The 2007 study suggests that training the muscles once or twice a week is sufficient to maintain them for at least 12 weeks.

Keywords

💡Resistance Training

Resistance training refers to exercise that causes the muscles to contract against an external load, such as weights or resistance bands. In the video, it is emphasized as a crucial component for optimal health and longevity. The script discusses how even with a busy schedule, incorporating resistance training can significantly reduce the risk of all-cause mortality and various diseases like cancer and diabetes, highlighting its importance in the context of the video's theme.

💡Muscle Strengthening Activities

Muscle strengthening activities are a subset of resistance training that specifically aim to increase muscle mass and strength. The video script cites studies showing that these activities are associated with a 15% lower risk of all-cause mortality, underscoring their health benefits and relevance to the video's focus on the effectiveness of minimal training sessions.

💡Mortality

Mortality, in the context of the video, refers to the incidence of death within a population. The script discusses how resistance training and muscle strengthening activities are linked to a reduced risk of all-cause mortality, which is a significant health outcome measured in the studies mentioned.

💡Optimal Health

Optimal health denotes the highest attainable level of overall well-being, both physically and mentally. The video emphasizes that resistance training is required for achieving optimal health, suggesting that even minimal doses of exercise can contribute to this state.

💡Longevity

Longevity is the state of living a long, healthy life. The video script mentions that resistance training is associated with longevity, indicating that engaging in such activities can potentially extend one's lifespan while maintaining good health.

💡Cardio

Cardio, short for cardiovascular exercise, refers to physical activities that strengthen the heart and lungs. The script suggests that combining cardio with resistance training can further reduce the risk of all-cause mortality, thus integrating it as a key element in the discussion of health benefits.

💡Bodybuilding

Bodybuilding is a sport that involves the development of muscle mass and aesthetic proportions through intensive weight training. The script mentions bodybuilding as a hobby, contrasting it with the minimal effective dose of resistance training needed for health benefits, to illustrate that extensive training is not necessary for everyone.

💡Diminishing Returns

Diminishing returns occur when the additional benefits from increased input decrease. In the script, this concept is applied to resistance training, explaining that doing more sets beyond a certain point does not proportionally increase muscle gains, which is a key point in the discussion of efficient training.

💡Meta-Analysis

A meta-analysis is a statistical technique used to combine and summarize the results of multiple studies. The video script references a meta-analysis of over 200,000 people to support the health benefits of muscle strengthening activities, demonstrating the scientific basis for the video's claims.

💡Training Close to Failure

Training close to failure means pushing the muscles to the point where they can no longer perform another repetition with proper form. The script discusses the importance of this concept for maximizing the efficiency of each set during resistance training, emphasizing the need for intensity to achieve gains.

💡Eccentric Part of the Lift

The eccentric part of the lift is the phase of a weightlifting movement where the muscle is lengthening under tension, typically as the weight is being lowered. The script advises to perform this part slowly to increase the effectiveness of each rep, illustrating the technique for maximizing muscle engagement and growth.

how long do you really need to spend in

the gym to reap all the benefits of

resistance trading and build muscles in

the gym most of us are busy

professionals working 40 hours a week or

even more and with latest research

stating clearly that resistance training

is required for Optimal Health and

Longevity how can you fit in working out

in hectic work and life schedule in this

video I want to explore the current

science literature on what is the

minimum effective dose you really need

to build muscles and for the health

benefits it provides before we start

diving into how long and what you should

be doing in the gym let's explore the

latest findings from this huge

systematic review and meta-analysis of

over 200 000 people done in 2021. seven

studies with more than 42 000 people

concluded that muscle strengthening

activities were associated with 15

percent lower risk of all cause

mortality 15 that's a huge number and it

gets better though three more studies

concluded that the joint benefits of

resistance training on cardio in more

than 500 000 participants concluded that

combining the two was associated with 14

lower risk of all cause mortality even

though that the mid analysis states that

the overall quality of the evidence is

very low these are insanely impressive

numbers and even if there is only maybe

a correlation here not a direct

causation this is still a good bulk of

evidence that resistance training and

doing cardio combined is really

beneficial and this is not only for all

cause mortality this is also for cancer

for diabetes there are really strong

evidence that doing resistance training

and cardio decreases these diseases by

up to 20 so how long and what kind of

weight lifting you should be doing to

get all these benefits just 30 to 60

minutes per week that can be done in one

of your lunch breaks or any time that

you're free for someone like me with a

busy job and a busy lifestyle is great

news now yes I do bodybuilding as a

hobby so I naturally I train longer but

this is just a choice at the end of the

day if you want the benefits you can

just do 30 to 60 minutes per week but

you still need to do your cardio and

it's better to combine both for all the

benefits and building muscle doesn't

really need you to go to the gym six

times a week and dedicating your whole

life to it as YouTube and Instagram and

social media in general is leading

people to believe so how long should you

really be training to build muscle now

this really depends on your mindset

there are two types of people people who

want to maximize their gains and people

who want to do just barely enough to get

the health benefits it provides the

current gem mindset right now is that

the more you do the more gains you get

but it's actually not the case not only

that there's diminishing returns as we

will see later also doing the minimum

doesn't really leave too much on the

table for example if doing four sets per

muscle group per week will give you 80

of the results doing eight sets will not

give you 160 of the results it would

actually give you 90 of the results or

even less if these sets are not done

close to failure and this is

demonstrated here in this meta-analysis

where they analyze 15 studies found out

that on average doing 10 says per week

promotion group yielded the maximum

results but doing five or less didn't

give you fifty percent of the results

but almost 70 percent of the results so

yes you can maximize your gains doing

more but doing less doing the minimum

will be enough for your given goals

because at the end of the day I believe

not all of us want to be 100 kg

bodybuilder just one thing to keep in

mind here is that these numbers are

averages so some people get more some

people will get less so for some

practical advice here if you have the

time and you want to maximize your gains

then doing 10 sets per muscle group per

week is the current Science Fitness

Community recommendation based on so

many studies but if you are pressed on

time and you have a hectic lifestyle and

you have a full-time job or you have

kids or what have you then doing five

sets or even three sets per week is more

than enough and it will be enough for

you to progress and see the health

benefits coming from resistance training

now some people tell me but I don't want

to spend two hours in a gym every time I

go I still spend two hours and anyway I

will give practical advice here but at

first I want to mention something almost

12 years ago an article was published by

Martin Birkin I would recommend reading

the whole day but I want to highlight a

few things from this article that I see

in in all the gyms I go to until this

day one is the illusion of complexity

you don't really need the latest

research on how to train to progress

I've seen this so many times people

doing some crazy Tech talk exercises

that doesn't benefit you in any way it

just looks fancy so sticking to the

basics is the best thing to do squats

bench press deadlifts will continue to

work until the end of time you don't

keep track getting muscles is quite a

simple concept your body needs stimulus

AKA training to build muscles but you

can give the stimulus all at once it has

to be weekly step-by-step process to

sort of convince your body to build the

muscles if you don't keep track of what

you're doing every week you won't

increase your loads the week after and

you will be spinning your wheels and

make no progress this is really

mind-boggling to me I don't really

understand it I've seen people people

going to the gym for years and they

still look the same and they have the

same strengths they don't increase

anything in any way and I don't

understand how is this motivating and

the only thing that impresses me is that

they are still motivated to the gym even

though they don't see any progress

lastly you are socializing too much if

you're pressed on time and you want to

be in and out of the gym in 40 minutes

in your lunch break it wouldn't make

sense to be socializing or be on

Instagram for 30 minutes you need to be

efficient and actually do the work that

will help you build muscles and progress

talking browsing social media isn't one

of them so enough ranting for now so

what are the practical things that you

can do right now to make your workout

more efficient and quick first cut the

warm up you don't really need 30 minutes

of warming up warming up your specific

muscle group that you're trading that

day is more than enough let's say you're

doing squats start with easy weight or

even without a weight do 20 reps and

then increase the weight and do more

until you reach your working weight

second do more supersets doing supersets

is best I've done was two different

muscle groups for example doing a bench

press and a pull down while you're just

taking a break you work your back or

doing biceps and triceps this can cut

your workout time significantly third do

a drop set drop sets again are an

amazing tool to cut time and increase

the volume in your workouts this can

increase your volume without doing more

sets all you have to do is pick the

weight you are doing this week and do a

set of failure then drop the weight 20

to 30 percent then do another set to

failure then drop it again and do

another set to failure just don't do

this with compound lifts especially

squats unless you have a death switch 4

doors post sets so this is similar to

drop sets but without dropping the

weight so you choose the number of reps

you want to do let's say 40 reps then

you do one set where you get as much as

you can then rest for 20 seconds then do

another and keep going until you finish

your 40 reps so this is a great tool

that I personally use to cut my workout

time it's like doing four sets in one

one caveat to all of this is that you

need to train close to failure but since

most of people don't know what failure

really is and based on these studies we

tend to underestimate failure by up to

five reps I have a recommendation here

you need to do everything super slowly

The Eccentric part of the lift or the

part where you feel the resistance

should take you at least three seconds

don't just drop the weight I want you to

feel it stretching feel the tension the

muscles yes it will hurt but the more it

hurts the more gains and benefits you'll

get and that's the mindset you want to

have going to the gym when the muscle

hurts and not because you are doing bad

form but because the muscle is getting

really worked and stretched out that's

where you will get all your gains you

know this famous quote no pain no gain

unfortunately it is correct and that's

what you need to do in the gym to cut

your workout really short because doing

less sets means that these sets needs to

be super efficient one thing I want to

mention here is maintaining your muscles

well you will be relieved that

maintaining muscles doesn't really need

as much much work as building it this

2007 study suggests that trading once or

twice a week is sufficient to maintain

your hard-earned muscles at least for

the 12 weeks they tested this in so you

really don't have to keep going to the

gym three four times forever to maintain

your muscles after you've built the

muscles you need for the health benefits

or the look you're going for you can

shift focus on other things or Hobbies

while still reaping the health benefits

that resistance training provides with

only going to the gym once or twice a

week I will leave all the studies I

mentioned in the description box below
