This challenge is the ultimate in bicep, tricep and upperbody workouts for those in a rush! All you need is a pull-up bar, chair and stopwatch. Your mission, should you accept it, is to complete the following exercises in as quick a time as possible:- 
50 Pull-ups (narrow or wide grip) 
50 Push-ups 
50 Chair Dips 
50 Chin-ups (narrow or wide grip) 
And it has to be in that order!!
