This 30-day program will help you increase your flexibility. The program utilises a mixture of active and passive stretching techniques to give you the fastest gains possible in the shortest time. While working on the splits you not only improve the flexibility of hamstrings, thighs, and hips but also promote better blood circulation to the areas most affected by the sedentary lifestyle. This guide will cover ways to increase flexibility in just ten minutes per day. But here’s the trick: you have to commit to stretching. Stay as consistent with a stretching routine as you would with a fitness routine or diet program. Our programs are especially designed for complete beginners, so take all the time you need in reaching your goal. Even if you are a bit more advanced, make sure you complete the warm up and each step daily to keep yourself injury free.
