1 set does not have to be 10 reps. But it does have to be close to muscular failure! So if you fail push-ups at 20 reps it’s time to consider using a more difficult push up. Like an archer push up, or some other variation that you PHYSICALLY FAIL at around 5-15 reps (10 is a good medium) If you do 10 of those sets a week.... You’ll be building muscle like there’s no tomorrow! Stay Flexy! #m#movementbydavids#stayflexyhomeworkout
