In this high-intensity interval workout, you will challenge yourself to do max rep push-ups and crunches. If you can do 10 reps / exercise, you will end up doing 50 push-ups and 50 crunches! Newbies can try this with kneeling push-ups.
We love these adjustable dumbbells from Rep Fitness. They take up very little space and are also very durable compared to other adjustable dumbbells on the market.
