The triceps extension smash uses a barbell in a squat rack to apply pressure to the triceps while moving through elbow flexion and extension. Tight triceps limit overhead lockout, front rack depth, and elbow health. This technique is particularly effective because the barbell provides consistent, targeted pressure across the entire muscle.

Setup

  1. Set a barbell in a squat rack at approximately waist height.
  2. Place the back of your upper arm (triceps) on the barbell, just above the elbow.
  3. Lean your body weight into the barbell to create pressure on the triceps.
  4. While maintaining pressure, slowly bend and straighten your elbow — this is the extension/flexion “floss.”
  5. Perform 8–10 elbow movements at each position, then shift your arm so the barbell contacts a different part of the triceps (closer to the shoulder).
  6. Work from just above the elbow to the lower portion of the deltoid insertion.

Coaching Cues

What to feel:

  • Deep pressure on the triceps muscle belly — not on the elbow joint
  • A stretching sensation as you flex the elbow while the tissue is pinned
  • Gradual release of tension through the back of the arm

Common mistakes:

  • Resting the elbow joint directly on the barbell — keep the pressure on the muscle, not the bone
  • Not using enough body weight — lean in; light contact won’t create meaningful change
  • Moving too quickly through the elbow bends — slow, controlled movements are more effective
  • Only working one section of the triceps — the muscle has three heads; cover the full length

Programming

Parameter Recommendation
Duration 60–90 seconds per arm
Sets 1–2 per side
Frequency 3x per week, or before pressing/overhead sessions
When to do it Upper body focus, full mobility session

Progressions

  1. Beginner: Use a foam roller on the ground instead of a barbell. Less intense pressure.
  2. Intermediate: Barbell in the rack with moderate body weight, full elbow flexion/extension range.
  3. Advanced: Barbell with maximum lean, adding wrist rotation and overhead reaching while pinned.
