Ready for another Rep challenge? I was so beat after the last one I created that you can see here, I decided to make another! Like the last one, complete 10 reps of each exercise before moving on to the next with NO rest in between. After you have finished the 10 reps of all 8 exercises, rest between 30-60 seconds and start the next round. Shoot for 5-10x thru. I used 15 pound dumbbells for the weights and completed 10 rounds in 44 minutes (this includes taking 30 seconds rest in between each round). Five rounds took me 21 minutes! Keep your form spot on, and only rest during the round if you absolutely have to.
