@drillsthenics: It is the link between your body and the bar. Weak grip can cap your pull-ups. Slow your muscle-up progress. Hold back weighted strength. Most people train back. Few train the thing that connects them to the work. Build grip with: • Time under tension • Harder variations • Progressive overload Dead hangs. Towel work. One-arm hangs. Fingertip progressions. Stronger grip = stronger upper body training. If your progress feels random, Strength System gives you clear progression. Link in bio.
