Hill Reps Find an outdoor incline steep enough that you feel a burn in your glutes as you walk to the top, but that you can walk to the top of without stopping. It should take between a minute and a half and 2 and a half minutes to reach the top. When you reach the top, walk back down to recover, then walk back up again. Repeat 10 to 12 times. Step Ups Begin your walk at a park with a bench or picnic tables or at a track with bleachers to use for step ups. Start walking from the bench, table or bleachers and walk for a quarter mile (once around the track). Then, turn around and walk back to the starting point. Perform 20 step ups, alternating legs each time. Repeat the half-mile walk and step-up cycle 3 times. This should take about 30 to 40 minutes. Sumo Squats on Hills Chose an outdoor walking route with plenty of hills. Whenever you reach the top of a hill, do 10 sumo squats. To perform a sumo squat, stand with your feet about 4 feet apart, toes pointed outward. Push into your heels and sit back, lowering your body until your thighs are parallel to the ground. Straighten your legs to return to the starting position. Walk to Lunge Begin walking on a trail, in a park or on a track and continue for 3 minutes. Then, do 30 seconds to a minute of walking lunges. To perform a walking lunge, take a giant step forward with your right leg and bend your knees to lower your body towards the ground. Stop before your back knee touches the ground. Push through your feet to raise your body back to the starting position. For the next lunge, step forward with your left leg. Walk for another 3 minutes, then stop again to perform a minute’s worth of lunges. Repeat the cycle 10 times for a 40-minute workout. Walk to Squat Begin walking on a trail, in a park or on a track and continue for 3 minutes. Then, do 30 seconds to a minute of bodyweight squats. To perform a squat, stand with your feet slightly wider than hip-distance apart. Bend your elbows and hold your hands together in front of your chest. Push into your heels and sit down, as if into a sofa, keeping your chest lifted. Stop when your thighs are parallel to the ground. Push through your heels to raise yourself back to the starting position. Walk for another 3 minutes, then stop again to perform a minute’s worth of squats. Repeat the cycle 10 times for a 40-minute workout.
