Frequently Asked Questions
How long should I rest between leg workouts?
Legs (especially after heavy squats or deadlifts) need 48-72 hours minimum. Beginners may need up to 96 hours. Legs have larger muscles that generate more damage and require longer to fully repair.
Can I work out a sore muscle?
Mild soreness (DOMS) is normal and light activity can help. But training a muscle that is still significantly sore can lead to overtraining and injury. Wait until soreness drops to about 20% before training that muscle again at high intensity.
