I've maxed out on my gains from body weight pullups ups and pushups. I workout 6 days a week and do 130 pullups on a back day and 350 pushups (half of them weighted) on chest day and then on a mixed day 100 squats and 200 pushups and core.

How to make workouts more gruelling? I use a backpack with 20kg weights on pushups. I'm 88.5kg and doing reps reps of 8 pullups. Max 15 bodyweight pullups.

I just want some tips on more difficult bodyweight exercises focused on size.
