A perfect egg for warmed-up hands. The Warm Up Egg is a warm-up and rehabilitation ball designed to protect, activate, and rehabilitate fingers. Developed with a physiotherapist (Julien Rémillieux), it offers ideal resistance for fragile joints. Use before climbing, after an injury, or daily to maintain your dexterity. Straight grip exercises: Along its long axis, the Warm Up Egg foam ball promotes interphalangeal grips for targeted finger work to prevent finger injuries when climbing, while improving grip strength. Arched and semi-arched exercises: Perfect for targeting the specific movements of climbers, the Warm Up Egg foam ball's small axis facilitates palmar grips, essential for effective osteoarticular warm-up.
