Dropping to your knees shortens the lever, making this the approachable version of the bodyweight skull crusher: you bend at the elbows and lower your upper body toward the floor, so your own weight is the resistance. Progress by moving your hands further forward, which lengthens the lever and can eventually outload most people's dumbbell extensions.
How to do the Kneeling Bodyweight Triceps Extension
- Kneel down on the ground with your knees hip-width apart.
- Place your hands on the ground in front of you, shoulder-width apart, fingers pointing forward.
- Extend your legs straight behind you, balancing on your toes and hands, forming a straight line from head to heels.
- Bend your elbows and lower your upper body towards the ground, keeping your elbows close to your sides.
- Pause for a moment at the bottom, then push through your hands to straighten your arms and return to the starting position.
- Repeat for the desired number of repetitions.
Tip: Keep a slight bend at the top on lying extensions to protect the elbow, but lock out fully on cable pushdowns.
Muscles worked
Primary
Triceps · Arms
The triceps straighten the elbow, and overhead variations stretch the long head at the bottom, so you should feel the whole back of the upper arm working with a hard squeeze at lockout.
Common mistakes
- Elbows flaring out — on overhead and lying extensions the elbows should stay pointed forward or up, not out to the sides, since flaring turns it into a press.
- Upper arm moving — the upper arm should be pinned in place and only the forearm should move; if the elbow drifts, drop the weight.
- Not finishing the rep — take every rep to a full triceps squeeze; on pushdowns that means a complete lockout for a count.
- Cutting the stretch — on overhead extensions let the weight travel down behind the head until you feel the long head stretch before pressing up.
Where it fits in a workout
Triceps extensions go after the presses in a push session or at the end of an arm day. Superset them with biceps curls.
