How many bench dips should I do?
You should try to do 10 to 15 repetitions of this exercise per set. Start off by doing two sets of bench dips in each of your workouts. Once you feel you can complete that with ease, move on to three sets of 10 to 15 reps, and then on to four sets.
How to do it: Stand facing away from a bench, grab it with both hands at shoulder-width. Extend your legs out in front of you. Slowly lower your body by flexing at the elbows until your arm at forearm create a 90 degree angle. Using your triceps lift yourself back to the starting position.
