Single-Arm Kettlebell Thruster
The single-arm kettlebell thruster combines a squat with an overhead press in one flowing movement. It trains your legs and shoulders while your core works to keep you upright under an uneven load.
Higher injury risk. Read the safety notes before adding weight.

How to do it
- Stand with your feet about shoulder-width apart, toes turned slightly outward.
- Use both hands to position the kettlebell at one shoulder, resting against your forearm with your working elbow close to your ribs.
- Lower your hips between your knees into a squat to a comfortable depth with your feet flat.
- Drive through your feet to rise quickly from the squat.
- Press the kettlebell overhead as you finish standing, using your leg drive to reach a straight-arm position.
- Lower the kettlebell under control to the same shoulder to finish the repetition.
Form cues
- Brace before each descent.
- Exhale as the bell rises.
- Let your free arm counterbalance you.
Common mistakes
- Leaning back at lockoutKeep your ribs over your pelvis by tightening your glutes as the bell reaches overhead.
- Letting the wrist fold backwardRest the handle diagonally across your palm so your wrist stays nearly straight.
- Knees collapsing inwardKeep your kneecaps tracking in the same direction as your toes throughout the squat.
Safety
A heavy or poorly controlled kettlebell can pull you off balance or fall from overhead. Fatigue and the offset load can also lead to twisting or excessive back arching, straining your shoulder or lower back.
- Practice with a light kettlebell before increasing weight.
- Use a clear area with enough overhead and side clearance.
- End the set when you cannot stabilize the bell overhead or control its return.
If squatting or reaching overhead causes shoulder, wrist, back, or knee pain, get advice from a physiotherapist before using this movement.
