How should I program the Cable Lying Triceps Extension — sets, reps and frequency?

As a single-joint isolation exercise, it responds well to a higher 10-15 reps for 2-4 sets, usually taken close to muscular failure. It tolerates higher frequency than a heavy compound lift — twice a week for the same muscle group is common. Add small amounts of weight or an extra rep once every working set can be completed with good form — the same progressive overload principle behind every strength exercise in the library.

How to do the Cable Lying Triceps Extension, step by step:

  1. Step 1. Lie on a flat bench and grasp the straight bar attachment of a low pulley with a narrow overhand grip. Tip: The easiest way to do this is to have someone hand you the bar as you lay down.
  2. Step 2. With your arms extended, position the bar over your torso. Your arms and your torso should create a 90-degree angle. This will be your starting position.
  3. Step 3. Lower the bar by bending at the elbow while keeping the upper arms stationary and elbows in. Go down until the bar lightly touches your forehead. Breathe in as you perform this portion of the movement.
  4. Step 4. Flex the triceps as you lift the bar back to its starting position. Exhale as you perform this portion of the movement.
  5. Step 5. Hold for a second at the contracted position and repeat for the recommended amount of repetitions.
