Training Tips:
1. Start with a gripper you can close for 5–10 reps before progressing.
2. Train grip 2–3 times per week to avoid overuse injuries.
3. Use techniques like “negatives” (slowly releasing a closed gripper) for strength gains.
4. Combine with other grip tools (pinch blocks, thick bars) for balanced hand strength.
