Kettlebell Curl
Kettlebell curls for an unusual biceps stimulus. It works mainly the biceps, with help from the forearm flexors.
Flawless ranks it by lifetime volume: Gold, the third of eight ranks, starts at 25,000 kg.
How to do Kettlebell Curl
- Stand tall with a kettlebell in each hand, underhand grip, arms straight, elbows at your sides.
- Curl the bells up towards the shoulders by bending the elbows only; the upper arms stay still.
- Squeeze at the top for a second, then lower over 2–3 seconds to straight arms.
- The bell hangs below the hand, which pulls the wrist open; keep the wrists straight and the grip firm.
These are the same steps you see in the exercise guide in the Flawless app.
