I have been working out for a year and have started to do more body-weight training four months ago. I want to achieve skills that are chest-, triceps- and shoulder-oriented. But I also want to get a strong dip. Is it then okay to train for planche in the morning, and then do dips later on the same day? For example, at 1 p.m. I do planche training, then at 9 p.m. I do dip training?
Working on the same muscles twice a day is perfectly fine, but you want to do it a certain way.. Leave at least 8 hours in between both workouts, and save all the hard exercises like ones with a lot of weight(in terms of bodyweight, ones like a planche is harder than dips), or compound exercises, and save isolation exercises and easier exercises for your night workout. What you're doing is fine, keep in mind working out twice a day may require you to recover more
