Also known as:Lying Triceps ExtensionFrench PressSupine Triceps Extension
Imagine a bear lying on its back, carefully lowering a log towards its snout, then pressing it back up with powerful paws. This movement isolates the triceps, building strength for all the heavy lifting a bear might encounter.
Instructions
- Lie on a flat bench with your feet planted on the ground and a barbell, EZ curl bar, or dumbbells held above your chest with arms fully extended.
- Grip the weight with hands shoulder-width apart and palms facing forward.
- Bend your elbows to lower the weight slowly toward your forehead or just behind the top of your head, keeping your upper arms stationary.
- Pause briefly at the bottom, then extend your elbows to return to the starting position.
- Maintain control of the weight throughout the movement.
Benefits
- Effectively isolates the triceps for targeted development.
- Improves lockout strength in pressing movements.
- Allows for progressive overload using various equipment.
- Builds arm size and strength.
- Can be performed with different angles and grips for variety.
Key Points
- Keep your upper arms fixed and elbows pointed toward the ceiling.
- Avoid flaring the elbows outward - keep them close to your head.
- Move only at the elbows; don't involve your shoulders.
- Use a spotter when lifting heavier weights for safety.
- Breathe in as you lower and out as you extend.
Common Mistakes
- Allowing the elbows to flare outward.
- Using too much weight, compromising form.
- Dropping the weight too far and risking head injury.
- Engaging the shoulders instead of isolating the triceps.
- Moving too quickly, reducing muscle activation and control.
