Before stretching, warm up with 5 to 10 minutes of light activity. It's usually best to stretch after a workout. Keep stretches gentle and slow. Don't bounce. Breathe through your stretches. If you feel pain, you've stretched too far.
Stretch until you feel a slight pull. Then hold the stretch for about 30 seconds. Repeat the stretch on both sides 2 to 4 times. Aim to stretch major muscle groups in your body at least 2 to 3 days a week.
If you have health conditions or injuries, talk to a healthcare professional or physical therapist about which stretches are right for you.
