"I've tried tons of different ab workouts, but this one was my favorite. It starts out easy to give you the confidence you need to keep going. Started only being able to do about 20 situps and week 2 is already 25, but the program breaks it into smaller sets and gives you rest breaks to build your stamina gradually. I'm now at 50 situps!"

Are you ready for the 200 Situps Challenge? Train your body and build up to completing 200 situps with same people that brought you the OFFICIAL #1 5K Training app C25K®.

Using a proven program, the 200 Situps Challenge builds and strengthens your core muscles, having you perform specific reps of situps with a period of rest in between.
Just simply follow and perform the instructed number of reps, and after 8 weeks, you will be able to do 200 situps straight!

Some major benefits of working out your core include:
◎ A strong core will help you carry out other activities with more ease, such as lifting a box or playing tennis.
◎ Performing a regular routine of situps helps sustain your overall health. Well-toned abdominal muscles improve your digestion and posture, which in turn helps to improve the flow of oxygen and blood throughout the body.
◎ Strong core muscles can prevent lower back pain.
