Today's exercise requires the use of a weight that you can hold in both your hands. A briefcase or laptop bag (not empty, however!) will work perfectly, as will a pair of dumbbells or anything else you can find around the office that's got a bit of substance to it. This exercise will work on toning your hamstrings.
Step 1: Stand up straight and hold your weight in both hands in front of you.
Step 2: Squeeze your posterior muscles.
Step 3: Bend forward at the hips.
Step 4: Keeping your back straight, lower the weight to the floor in one fluid movement.
Step 5: Again, in a single fluid movement, lift the weight back up to the starting position.
