Stiff legged deadlifts are an isolating exercise which are great when used as an accessory to squats and deadlifts. They target the hamstrings and glutes as well as the back and core. They are also great for stretching out tight hamstrings at the end of a tough leg workout.
You can use a barbell, kettlebell, or dumbbells for this exercise. To perform, hold the barbell or dumbbells in front of you and, with a slight bend in your knees, bend forward until the barbell or dumbbells touch the floor. Keep your back flat and straight and suck your stomach in tight to keep your core controlled. Keep your chin up and look straight ahead of you. Squeeze your hamstrings and glutes as you come back up as it is these muscles which are doing the work. Take this exercise slowly and really feel the muscles working. Make sure you straighten your back all the way out when you stand up straight.
