This no equipment workout kicks my a$$ and I actually love it. I find it rather difficult to work my arms without equipment, you know what I mean? Two training components I implement to create an arm burn is that I’ll complete higher reps to make a bodyweight movement more challenging and I add in a lot of push ups: the ultimate upper body movement. I also included exercises that recruit the abs and rev up the heart rate to make this workout top notch. I suggest completing as many rounds as possible in 25 minutes but adjust the timeframe as needed: 15 minutes if that’s all you have or 35 minutes if you want a longer workout.
