A good exercise for hamstrings is to bend

[Jick 1986]

 Even if you forget to do the stretches before beginning the jogging, Action Fuel PRO stop and stretch before going on, then return to the jogging once the muscles are warmed up and loose.Hamstrings from the waist and touch your toes. Each stretch should be held for up to 30 seconds and it is important to remember to take full breaths. Also, it is important to avoid locking the knees and certainly do not bounce.
