The bodyweight kneeling triceps extension is an upper-arm exercise that isolates the triceps brachii using only your body weight as resistance. From a kneeling position you lower your torso by bending at the elbows, then press it back up under control, making it a joint-friendly way to build triceps strength with no equipment.
How to do the Bodyweight Kneeling Triceps Extension
- 1Kneel on a mat with your knees roughly hip-width apart and your hips, torso, and head stacked in one straight line.
- 2Set a sturdy bench, box, or low bar in front of you and place your forearms or hands on it at about shoulder-width.
- 3Brace your core and squeeze your glutes so your body stays rigid from your knees to your head.
- 4Keeping your upper arms fixed, bend at the elbows to lower your torso toward the surface under control over 2–3 seconds.
- 5Lower until your elbows reach roughly a 90° angle, keeping your elbows tucked close to your sides.
- 6Press through your hands and extend your elbows to drive your torso back up to the start, contracting the triceps hard at the top.
- 7Keep your hips locked in line throughout — avoid bending or piking at the waist.
- 8Complete your reps, then sit back onto your heels to rest between sets.
Form tips
- Keep your upper arms still and let the movement happen only at the elbow joint so the triceps do the work.
- Maintain a straight line from knees to head; squeezing your glutes and bracing your abs stops your hips from sagging.
- Control the lowering phase rather than dropping — the slow eccentric is where much of the triceps growth comes from.
- Make it easier by walking your knees forward (more upright) or harder by setting them further back so you lean into the movement more.
- Use a padded mat under your knees to stay comfortable across higher rep sets.
Common mistakes
- Letting the hips pike or sag instead of holding a straight line, which shifts load off the triceps and strains the lower back.
- Flaring the elbows out wide, which reduces triceps tension and stresses the shoulder and elbow joints.
- Using a short, partial range of motion, so the triceps never fully lengthen or shorten and the rep does little.
- Rushing the lowering phase and bouncing out of the bottom, which removes muscular tension and risks the elbow joint.
- Driving with momentum from the torso or shoulders rather than extending the elbows, cheating the triceps out of the work.
Frequently asked questions
What muscles does the bodyweight kneeling triceps extension work?
It targets the triceps brachii, the muscle on the back of the upper arm responsible for straightening the elbow. Because it is a self-loaded extension, the triceps do nearly all of the work.
Is the kneeling triceps extension good for beginners?
Yes. Kneeling shortens the lever and uses only your body weight, so it is gentler than a full-bodyweight version. Walk your knees more upright to make it easier, then lean back further as you get stronger.
How many sets and reps should I do?
For most lifters, 3–4 sets of 8–15 controlled reps works well. Adjust the difficulty by changing how far back you kneel so you reach near failure within that range.
How do I make the kneeling triceps extension harder?
Set your knees further back so your body leans more into the movement, slow the lowering phase, or pause for a second at the bottom of each rep to increase time under tension on the triceps.
Where should I feel this exercise?
You should feel it in the triceps along the back of your upper arms, especially as you press back up to full elbow extension. If you mostly feel it in your shoulders or lower back, fix your elbow position and keep your hips in line.
