Is stretching really necessary?

[dharani0022]

A yogi favorite, this pose focuses on hip and shoulder mobility, while Stretching your hamstrings, lats (muscles in your mid-back) and deltoids (muscles in your shoulders). Start in plank position with shoulders directly over wrists . Push your hips up toward the ceiling so you form a triangle with your body. Keep your head between your arms and straighten your legs as much as possible. Reach your heels toward the ground and spread your fingers, so your bodyweight gets distributed evenly through the hands and feet.
