Summary
This short tutorial from Jeff Cavaliere (ATHLEAN-X) demonstrates how to train the forearms at home using nothing but a standard folding chair. By adjusting your grip position on the chair, you can modulate the difficulty of the movement to create sufficient mechanical overload for muscle growth. The video emphasizes that lack of equipment is no excuse to skip forearm training.
Key Points
- Gym forearm work is often incidental — carrying dumbbells, loading barbells, and farmer’s carries naturally stimulate the forearms, but home trainees miss out on this.
- A single folding chair is all you need to perform direct forearm work at home.
- Grip position determines difficulty — holding closer to the seat (the arms of the chair) reduces the load, while gripping further away (the top of the chair back) significantly increases it.
- Flipping the chair upside down and gripping the crossbar at the bottom provides a third variation, allowing you to tilt the chair away to work the forearms from a different angle.
- Progressive overload is the core principle — Jeff notes he could barely complete 7 reps from the hardest grip position, confirming the stimulus is sufficient for growth.
- The specific tool matters less than the overload — as long as you are challenging the muscle progressively, growth will follow regardless of the equipment used.
Exercise Details
Chair Forearm Extension (Three Difficulty Levels)
Target Muscles
- Forearm extensors
- Muscles involved in radial deviation
Variations & Form Cues
-
Easy — Grip the chair arms (handles):
- Hold the side handles of a folding chair
- Keep elbows tucked in at your sides
- Tilt the chair upward through forearm extension
- Shorter lever arm = less resistance
-
Moderate to Hard — Grip the top of the chair back:
- Hold the top rail at the back of the chair
- Same tilting motion upward
- Longer lever arm dramatically increases difficulty
- Adjust hand position slightly inward if full range is not yet achievable
-
Variation — Inverted chair grip:
- Flip the chair upside down
- Grip the crossbar at the base
- Tilt the bottom of the chair away from you
- Targets forearms from a slightly different angle
Common Mistakes to Avoid
- Choosing a grip that is too easy and not providing sufficient challenge
- Ignoring the principle of progressive overload — always aim to increase difficulty over time
Sets/Reps
- No specific sets prescribed, but Jeff uses his own inability to exceed 7 reps from the hardest grip position as a benchmark for an effective overloading stimulus
