Bicep Curl on Stability Ball with Leg Raised

Muscles worked

The prime mover is the biceps brachii, which bends the elbow and rotates the forearm palm-up.

Even with a single joint doing the moving, the muscle is not working alone — the hamstrings assist hip extension and slow the knee down; the forearms hold the grip, which is often what gives out first; the quadriceps straighten the knee and take load on the descent.

The calves take a share of the work as well.

How this movement works

Everything happens at one joint. That gives you direct control over where the tension sits; the trade-off is that the muscle gets no help, so the load that feels hard here is a fraction of what a multi-joint version of the pattern would take. Slow, complete repetitions beat heavy ones.

It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.

What you need

Dumbbells let each side work on its own, surfacing a strength difference between limbs that a barbell would quietly cover for, and leaving the wrist free to rotate through the movement.
