Combining a forward lunge with an overhead extension turns an arm isolation into a full-body coordination drill: the lunge taxes your legs and balance while your triceps work overhead with elbows pinned by your ears. Keep the dumbbells light; the overhead position, not the load, is the challenge, and it fits circuits better than arm days.

How to do the Dumbbell Lunge with Triceps Extension

  1. Stand with your feet shoulder-width apart, holding a dumbbell in each hand.
  2. Take a step forward with your right foot, lowering your body into a lunge position.
  3. Keep your back straight and your chest up.
  4. Extend your arms straight overhead, keeping your elbows close to your ears.
  5. Lower the dumbbells behind your head by bending your elbows.
  6. Pause for a moment, then straighten your arms to return to the starting position.
  7. Repeat the movement for the desired number of repetitions, then switch legs and repeat.

Tip: Keep a slight bend at the top on lying extensions to protect the elbow, but lock out fully on cable pushdowns.

Muscles worked

Primary

Triceps · Arms

The triceps straighten the elbow, and overhead variations stretch the long head at the bottom, so you should feel the whole back of the upper arm working with a hard squeeze at lockout.

Secondary

  • DeltsThe front delt holds the upper arm in position on overhead extensions and should feel tension but not be lifting.
  • Abs

Common mistakes

  • Elbows flaring outon overhead and lying extensions the elbows should stay pointed forward or up, not out to the sides, since flaring turns it into a press.
  • Upper arm movingthe upper arm should be pinned in place and only the forearm should move; if the elbow drifts, drop the weight.
  • Not finishing the reptake every rep to a full triceps squeeze; on pushdowns that means a complete lockout for a count.
  • Cutting the stretchon overhead extensions let the weight travel down behind the head until you feel the long head stretch before pressing up.

Sets, reps and where it fits

Triceps extensions go after the presses in a push session or at the end of an arm day. Superset them with biceps curls on the same cable stack or with the same dumbbells.
