Light Weights vs Heavy Weights for Muscle Growth

Conventional wisdom has us convinced that high reps and light weights builds muscle endurance and makes little contribution to gains in muscle mass. However, is this a valid perspective? Well, to determine if heavy and light weight training cause different effects, we need to look at the research. After reviewing the research out there, it seems that using heavy or light weights actually doesn’t matter much in terms of hypertrophy. Studies show that muscle growth tends to be equal despite using light weights or heavy weights (high rep vs low rep). But this is only true when going to near failure, and one benefit of lifting heavy weights is the better strength gains you see when compared to light weights. Based on this, as you’ll see in my video, your best bet is to incorporate high reps with light weights AND low reps with heavy weights into your workout. This will enable you to target both metabolic stress and mechanical tension; both are important mechanisms of muscle growth.

    Bodybuilders lift heavy because they take a heavy dose of steroids.

    I think it very son the person. Like I’m 6’3 so if I lift light weights I won’t feel or see improvements because my limbs are long af. But when ever I lift heavy I get soar and see improvements fast. If you lift light at first you won’t grow as big but if you lift heavy I think you’d grow hella.

    It's better to use heavier weights and less reps than lighter weights and more reps.

    Extremely curious about your team? Who does the research? Writes the script? Does the illustrations? And how’d y’all come together? 🙋‍♂️🤷‍♂️🤔

    thing i learned on myself is that my muscle grow so fast no matter i use heavy or light if i made good pump in my muscle and do repetitions until i feel a bit pain …then i stop and rest muscle….and results are amazing ….food is btw 90% of job ….eat good food and gg

    So do heavy weights to shorten your rep range to failure.

  12. mudducks 84 says:

    I alternate days on my heavy my light and my cardio I do all three five days a week for about an hour to an hour and a half a day

  13. Con Job says:

    I want to be lean and cut. Not some big juice head walking around with concrete deodorant.

  20. Tim Dwyer says:

    You want to get stronger focus on pause reps. Dont worry about amount of reps , rep until failure, always push yourself, you can use methods like reverse pyramids. Use heavy weight and lightweight but always make it difficult on yourself no matter the method.
