I could be wrong here but I did it for a couple weeks and it didn't seem to be an issue. Best thing to do is just try and see. You have to remember to jump less each time and slow the descent more each time. You'll either get stronger at them or you'll regress and then you'll know! One thing I can say for certain is mix chins with pull ups. I made that mistake. So maybe chins twice a week and pull ups once and alternate them
