This routine consists of ten exercises, done 25 repetitions at a time, in four rounds. Altogether, this is a roughly 500-700 calorie workout (if you do it twice) that takes about an hour total to complete, though your exact calorie burn & completion time will depend on how fit you are and how quickly you complete all of the reps.

Some of these exercises are not overly difficult, but after 25 repetitions (especially after 4 rounds of 25), your muscles are going to start protesting a bit. Push through it and you will be increasing your cardio threshold, as well as toning your entire body.

There are a number of ways that you can break up this 100 Rep Workout; we recommend that you do half of it (50 reps) at a time, twice daily. The video is roughly half an hour long and only goes through half of the repetitions of the entire routine; if you want to do the full 100 repetitions in one fell swoop, all you need to do is start the video over again.

When you break your exercising regimes up into two separate segments, you are going to end up burning more calories than you would if you did the same amount of activity in one single session.

Another reason why this 100 repetition routine burns so many calories is because of all of the large muscle groups involved.

This routine is easily adaptable to suit any fitness level; do the easiest versions of the exercises if you’re a beginner, and add extra weight if you’re at a more advanced fitness level.

If you can’t quite do 25 of each exercise every round, push yourself to do as many reps as you can. After doing this routine on a regular basis, it shouldn’t be long before you gain strength and cardiovascular endurance and it will become a bit easier.

Make sure that you warm up with at least 5 to 10 minutes of cardio before jumping into these rigorous exercises in order to prevent injury and muscle strains.
