Lighter weights lots of reps whats the real story

[zod]

Hello all,

Having some issues with my arm these days. Doctor wants me to take it easier on some aspects especially heavy weight lifting. He thinks lighter weights would be easier for a while.

In the case of lighter weights and more reps what is the benefit, I used to hear that it was great for cutting but from what I know these days that isnt the case, it really comes down to body fat %.

So who can give me the low down on what lower weights and lots o reps do for you.

Thanks Thanks

it would be good for endurance, to learn proper form and maybe to work through an injury? not sure about the last one.

It might be better for sarcoplasmic mass. What's wrong with your arm?
