Are there any ways to gain muscle without weights?

Force yourself to constantly have seizures.

if we're being obtuse, no

But yeah. You've got mass. Muscle gain is caused by muscle fatigue. Do shit like pullups and pushups and eat well.

roids
if you blast test and tren while eating enough food and protein, you'll get big
not as big as you could get if you were training AND roiding, but still pretty big

gymnastic strength training

Bodyweight exercises with increasingly strong resistance bands.

This is the only proper answer and with four 4's, it confirms it

But /fit/ told me pushup doesn't work.

It does but it's a super shitty option if you're a fat fuck and can be really awkward to adjust it to actually be useful.

The simple answer is body weight exercises. There are plenty of them. There's just a different type you need to work on if you're a lardass vs a skeleton, so lardasses often try to do the skinny skeleton ones and get discouraged. Or some skinny skeletons expect to do full sets of body weight exercises instead of working up to it.

Yes you need to alter your testosterone levels. As you may have noticed black people tend to hold muscle better because they have higher testosterone.

You may have seen some black homeless dude and he is still shredded and big.

In short, masturbating once a week has shown to increase test levels by 145% so if you did that you would naturally get bigger over time.
