People often assume that the only way to build strength is by using gym machines or heavy barbells. But you can increase muscle mass in your legs using dumbbells—whether that's using the racks in a gym or a pair of adjustable dumbbells at home.
Strength and Pilates coach Courtney Fisher recently shared a workout that shows how to use dumbbells to effectively train your glutes, hips, hamstrings and calves. There are also unilateral (single-leg) exercises in the routine which are great for people who like running and hiking, where your body continuously needs to be stable and balanced on one leg.
