Side Lunges target the quads, abductors, glutes and hamstrings. As runners we rarely move laterally (sideways) so this is a great exercise to improve our balance and coordination.
Clasp your hands together in front of your chest and roll your shoulders back so you have a tall posture and the chest is open. At all times, keep your toes pointing forward as you take a side step out to the right so you feel a stretch on the left inner thigh. Pause for 1-2 seconds at the bottom and then push back up to the starting position. Repeat on the same side of the instructed number of repetitions.
Remember to looking forward throughout the movement. Avoid letting your gaze drop towards the moving leg.
