There's a reason you should never skip leg day: Your lower-body muscles power all your daily movements from walking to climbing stairs to getting up off the couch. Keeping them strong is imperative to staying active while remaining injury-free.

"You'll be able to walk, climb, run or bike without getting tired quickly," says Mathew Forzaglia, certified personal trainer and founder of Forzag Fitness on the NEOU App. "Plus, working out our legs — which is one of our bigger muscle groups — will help us burn more calories, as having more muscle will keep your body burning all day long."

And while body-weight exercises like squats and lunges are great for beginners, adding dumbbells to those exercises helps you build muscle and get stronger even faster. That's because your muscles need a challenge: Eventually, they adapt to your workout and you have to up the ante so they're forced to grow.

The four exercises below (plus one bonus ab exercise) from Forzaglia, our 30-Day Dumbbell Challenge host, target all the muscles in your lower body. You'll do this workout every time our 30-day calendar says "Legs." Remember, every six days, the rep scheme changes so that you're doing the following:

  • Round 1: 2 sets of 10 as a circuit, doing one exercise after another
  • Round 2: 2 sets of 12 as a circuit
  • Round 3: 2 sets of 15 as a circuit
  • Round 4: 3 sets of 10, doing all sets of an exercise back-to-back with 30 seconds rest between sets
  • Round 5: 3 sets of 12 back-to-back
