While it's tempting to push yourself every day, rest days are just as crucial as workout days for achieving fitness goals. Rest allows your muscles to repair, rebuild, and grow stronger, reducing the risk of overtraining and burnout. During periods of rest, your body replenishes energy stores and restores hormonal balance, which is essential for progress. Incorporating at least one or two rest days into your weekly routine promotes recovery, prevents injuries, and can actually help improve performance when you return to training.
