This 2 day workout is a great starting point for any beginner but is also a fantastic challenge for any avid gym goer looking to build muscle and gain strength. The workouts are simple and there are only two of them to alternate between - Workout A and Workout B. There is no time frame on this and these workouts can be completed indefinitely. You may notice a large disparity between minimum and maximum repetitions - this is to take into consideration different levels of fitness and strength between individuals. For an extra challenge, each time you go through my calisthenic workout, try and complete more repetitions of each exercise than you have ever managed previously.
