Well, it really depends on how much you can take. If you think you can do 250 three times in a row in 60 minutes go for it, but there is a slight chance you will be sore. If you want to increase how your calisthenics limit then you should gradually add more. So if you can only do 20 squats without feeling a strain on your legs then work your way up to 25 then to 30. That is the best way to do it, or you can make a goal to do 50 squats a day and do 10 squats sets throughout the day.
