** PLEASE NOTE a warm up and cool down are not included. Welcome to this low intensity and specific hamstrings workout to target all 3 muscles of your hamstrings. The hamstrings enable the knees to bend and play an important part in walking, running and squatting for example. Many hip and knee issues result from weak hamstrings. You’ll need some dumbbells, a barbell, weight ball, 2 tea towels or body weight is just fine if you are new to these types of exercises.
