As we know dips are a great workout exercise, they're the squats of the upper body. I'm a 5'6" 40yr old male that is in decent shape, - I do strength workouts for specific muscle areas as well as a crossfit workout at least once a week. (my cardio still sucks however lol). When it comes to dips, I do 3 sets of 15-20. I haven't tried to do a straight "to failure" amount yet. So I'm wondering is there a certain amount of dips that correspond to certain level of fitness?
