The triceps actually make up the bulk of your upper arm.  Triceps are the big, primary movers for upper-body ‘push’ motion, meaning extension of the arms. The most common mistake beginners make is ignoring their triceps.

The second most common mistake? Overworking your triceps—that is, not recognising the work triceps do while you’re bench pressing. Do this beginner-focused triceps workout once or twice a week, but make sure you don’t to it the day after you focus on a chest-heavy workout.

Directions: 

Aim for four sets of 12–15 reps, with just 15 to 30 seconds of rest between sets. (Increasing muscle mass requires volume.) Use a load heavy enough so it’ll be challenging to complete your reps, but not so heavy that you can’t maintain good form.

For the sake of clarity: “Upper arm” refers to the part that’s closer to your shoulder. Looking to boost the size of your arms without doing a ton of biceps curls? This is the perfect workout routine to start.

4. Bench Dip

How to:

  • Ditch your weights and sit on your bench sideways, hands holding the edge next to your hips.
  • Keep your knees bent (which is easier) or extend your legs (which is more difficult).
  • Move your hips up and forward off the bench, so your body is largely supported by your arms.
  • Bend your elbows back, aiming for right angles; press up to straighten.
