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.
Always Warm Up. Always spend 10 â 15 minutes performing light activity to warm up your muscles before you start stretching. After your workout, during your cool down, is the ideal time to train to do the splits because your muscles will be warm and pliable. If you havenât just completed a workout you can perform 15 minutes of jogging, jumping jacks, squats and lunges to get the blood flowing and loosen those muscles up.
