The FLEXORS in your arm are activated when you squeeze, and the EXTENSORS activate when you open your hand. Lifting weights ONLY engages your flexors, causing a musculature imbalance in our forearms, which over time leads to strained muscles and tendons followed by pain in the surrounding joints. We recommend training both regularly.
