Squat
Works: The glutes, hamstrings, and quads (quads are the primary muscles used for running uphill).
To Do: While holding dumbbells and keeping your feet shoulder width apart, shift your weight to your heels as you lower into a seated position. Keep your eyes forward and descend until your hamstrings are parallel to the ground before you stand back up. Do 25 reps at a controlled pace.
Deadlift
Strengthens: The glutes, hamstrings, and calves, which give you stability and control on downhills.
To Do: Stand with feet shoulder width apart. Bend at the waist and knees and pick up a pair of dumbbells from the floor. As you stand up, pinch your shoulder blades together. Then lower back down, tapping the dumbbells on the ground before standing back up. Do 25 reps at a controlled pace.
Step Up
Develops: Powerful quads for stronger hill climbing.
To Do: Holding dumbbells, place your right foot on a box or step. Drive your weight into your heel as you step up. Squeeze your glutes at the top. Step back down in a controlled manner. Repeat with the left foot. Complete 20 total reps, alternating legs.
Forward Lunge
Builds: Stability and strength that helps you maintain good running form while going up and down.
To Do: Start with your feet pointing straight ahead and holding dumbbells. Step forward with your left foot, then bend the left knee until the hamstring is parallel to the floor. Your right knee should touch or come just above the ground. To avoid injury, make sure the left knee stays behind the toes. Step back up and repeat on the other side. Complete 20 total reps, alternating legs.
