You'll need a set of light dumbbells and a step. Targets glutes, quads, hamstrings, hips, core. Alternate sides until you've done 16 total reps.
Skater's Lunge: You will need a set of 3 or 5-pound dumbbells for this exercise. Holding the dumbbells at your hips, stand on a step bench or stair with your feet shoulder-width apart. Leaning forward slightly, lunge back with your left leg. Then, bring your left foot back on to the step and do a squat. Now lunge back with the right foot. You'll continue alternating legs until you've done 8 reps on each side. When you're lunging, your front leg should be bent 90 degrees with your knee aligned over your ankle. Remain in a low position as you bring your rear leg back on to the step. Then, when you squat, lower your self down about 2 more inches and hold that position for 1 or 2 counts. The skater's lunge targets your glutes, quadriceps, hamstrings, hips, and core. If you wanna make this exercise easier, don't hold weights and bend your front knee only 45 degrees when you lunge.
