We know why so many of us skip leg day: It's damn hard if you do it right. “Lower body is one of the most difficult muscle groups to train,” says Sam Simpson, an exercise physiologist, personal trainer, and owner of the Miami-based B-Fit Gym. Because leg muscles are large, working them feels more taxing than targeting the arms, abs, or shoulders, and it can leave you gasping for air. But that's simply your body burning a ton of calories — a good thing.
To make leg day really count, don’t waste your time on isolation exercises that only hit one muscle group (like calf raises) or machines that don't challenge your range of motion and stability. Instead, add a mix of the 10 expert-picked moves below. Performing three sets of 12 reps is always a safe bet.
