After every workout it is essential to stretch. Whether it's 5 minutes or an hour. Put time aside to release the lactic acid build up from your muscles and just stretch. This is a 14 minute stretch that can be done at home or right after your workout. Those who have low back issues, this stretch series is great for you! There is a lot of stretching of the hamstrings and gluteus Maximus that can release the tension to that tight low back.
