Get a leg up
Lunges work muscles in the lower body, such as the thighs, hamstring and buttocks. But they can be a bit of a strain on the knees, so start with smaller steps and don’t bend your knees beyond 90 degrees.
To begin, keep your upper body straight and relaxed. Then step forward, lower your torso and get the back knee to the ground. The front knee should be aligned with the ankle and not pushed out too far. Once in position, immediately get back up and move the back leg forward. Repeat 15 times. HIGH KNEES
The high knees exercise combines static running with exaggerated knee lifts. As you run in place, raise one knee up to waist-height and toward your chest, and then place it down before raising the other. Use your hands to guide your legs as you move. Repeat 10 times.
