The best time to do flexibility exercises is when your muscles are already warm so they can stretch farther without tightness or pain. If youâre doing only stretching exercises, warm up with a few minutes of easy walking first to warm up your muscles.
Itâs good to stretch when youâre cooling down because your limbs, muscles and joints are still warm. Stretching can help reduce the buildup of lactic acid, which can lead to muscles cramping and stiffness. Tips: Walk for about 5 minutes, or until your heart rate gets below 120 beats per minute. Stretching: Hold each stretch 10 to 30 seconds. If you feel you need more, stretch the other side and return for another set of stretching. The stretch should be strong, but not painful. Do not bounce. Breathe while youâre stretching. Exhale as you stretch, inhale while holding the stretch. So do your body a favor.
