Reverse tricep pulldowns (often referred to as reverse-grip tricep pushdowns) primarily target and activate your entire triceps muscle, but specifically place the most significant tension and focus on the medial head of the triceps.
Understanding Your Triceps Muscle
The triceps brachii is a large muscle on the back of the upper arm responsible for extending the forearm at the elbow joint. It's composed of three distinct parts, or "heads," each originating from a different point and merging into a common tendon that inserts into the elbow:
- Long Head: Originates from the scapula (shoulder blade), making it the only head that crosses the shoulder joint. This allows it to contribute to shoulder extension and adduction.
- Lateral Head: Originates from the upper part of the humerus (upper arm bone). It's typically the most visible head and contributes significantly to the horse-shoe shape of the triceps.
- Medial Head: Originates from the lower part of the humerus, closer to the elbow joint. This head is largely covered by the long and lateral heads but plays a crucial role in elbow extension, especially at the end range of motion.
The Focus of Reverse-Grip Tricep Pulldowns
While any triceps exercise will engage all three heads to some extent, the reverse grip (supinated grip, palms facing up) on a cable pushdown machine strategically alters the biomechanics to emphasize the medial head. This particular head runs from the middle of the tricep down to the elbow joint, and the reverse grip helps isolate its contribution to the extension movement.
This emphasis is beneficial for:
- Complete Triceps Development: Ensuring all three heads are adequately worked for balanced muscle growth and strength.
- Targeted Weakness: Addressing any potential underdeveloped medial head, which can contribute to overall arm size and pressing strength.
- Elbow Health: Strengthening the muscles around the elbow joint.

How to Perform Reverse Tricep Pulldowns Effectively
To maximize the benefits and target the medial head effectively, consider these practical tips:
- Setup: Attach a straight bar or EZ bar to a high cable pulley. Grip the bar with an underhand (supinated) grip, hands shoulder-width apart or slightly narrower.
- Stance: Stand facing the machine with a slight lean forward, feet shoulder-width apart, and a soft bend in your knees.
- Execution:
- Keep your elbows tucked close to your body and minimize shoulder movement.
- Extend your forearms downwards, pushing the bar towards your thighs until your arms are fully extended.
- Squeeze your triceps at the bottom of the movement, focusing on the contraction in the medial head.
- Control the weight as you slowly return to the starting position, allowing your triceps to stretch.
- Avoid Swinging: Use controlled movements to ensure the triceps are doing the work, not momentum or other muscle groups.
- Rep Range: Typically performed for 8-15 repetitions per set, depending on your training goals.
Benefits of Including Reverse Tricep Pulldowns
Adding this exercise to your routine offers several advantages:
- Comprehensive Triceps Activation: While emphasizing the medial head, it still contributes to overall triceps engagement.
- Variety in Training: Helps to introduce a different stimulus compared to traditional overhand grip pushdowns, preventing plateaus and ensuring well-rounded development.
- Improved Pressing Strength: Stronger triceps, including a well-developed medial head, directly translate to better performance in exercises like bench press, overhead press, and dips.
- Enhanced Muscle Definition: Targeting specific heads can lead to more sculpted and defined arms.
Triceps Head Activation Comparison
| Triceps Head | Primary Activation (General) | Emphasis with Reverse-Grip Pulldowns |
|---|---|---|
| Long Head | Overhead extensions, close-grip BP | Moderate |
| Lateral Head | Standard pushdowns, dips | Moderate |
| Medial Head | Any elbow extension, end range | High (Key Focus) |
By understanding which part of your triceps this exercise targets, you can strategically incorporate reverse tricep pulldowns into your arm workout for more balanced and effective muscle development.
