Setup
- Set an incline bench to an angle between 45 and 60 degrees.
- Sit on the bench with your back and head firmly against the pad and your feet flat on the floor for stability.
- Hold a kettlebell in each hand with a neutral grip (palms facing in), letting your arms hang straight down toward the floor.
How to do it
- Exhale and curl one kettlebell toward your shoulder, rotating your wrist so the palm faces up (supination) as you lift.
- Squeeze the bicep hard at the top of the movement while keeping your elbow pinned in place.
- Inhale and slowly lower the kettlebell back to the starting position using a controlled 3-second tempo.
- Repeat the movement with the opposite arm, alternating sides until the set is complete.
Form checklist
- Keep your elbows stationary and pointed toward the floor; do not let them swing forward.
- Maintain full contact between your shoulder blades and the bench throughout the set.
- Fully extend your arm at the bottom of each rep to capitalize on the weighted stretch.
- Avoid 'cheating' by arching your lower back or swinging the weights.
Pro tips
- At the top of the curl, try to turn your pinky toward your shoulder to maximize the peak contraction of the bicep.
- The kettlebell's weight hangs below the handle; use this to your advantage by letting it pull your arm into a deep stretch at the bottom.
Make it harder
- Implement a 'pause at the peak,' holding the contraction for 2 seconds on every rep.
- Slow down the eccentric phase to 5 seconds to increase metabolic stress and time under tension.
