The Best Fat-Loss Workout of All Time

This exercise targets the glutes and hamstrings, giving perfect definition and lift to your booty.

How to do it: Grab a pair of dumbbells with an overhand grip and hold them at arm's length in front of your thighs. Stand with your feet hip-width apart and your knees slightly bent. Shift your weight into one leg. Without changing the bend in your knee, bend at your hips and lower your torso until it's almost parallel to the floor (keep the weight as close to your body as possible). Pause, then return to standing. Your back should stay naturally arched during the entire movement. Do 8 reps each side.

These powerful jumps blast calories and engage every muscle in your body.

How to do it: Come into a lunge position with both knees bent. Make sure your front knee is directly above the ankle. Bring both arms back as you lower down into a lunge. Explosively, jump off the ground and switch feet in the air. Land softly in a lunge position with your other foot forward. Keep switching at a quick pace. Make sure to keep your chest lifted and swing your arms forward as you jump. Do 5 jumps per side.

Squats are excellent for slim thighs, a tight butt, and sculpted hamstrings. By adding the press, the core and shoulders are engaged the entire time.

How to do it: Grab a set of dumbbells and stand with your feet hip-width apart. Bend your elbows and bring the weights to shoulder height. Lower down into a squat by shifting hips back, like you are sitting in a chair. Come back to standing and press weights directly overhead. Lower the weights back to shoulder height as you immediately lower into your next squat. Continue the movement at a quick pace for 10 reps.

Similar to other jumps, this exercise burns calories quickly, keeps your heart rate up, and engages every muscle. Broad jumps will also improve overall athletic performance.

How to do it: Stand with your feet hip-width apart, knees slightly bent. Quickly extend your arms behind you while bending knees even more. Explosively jump forward (as far as you can) while swinging your arms forward. Land softly (by bending your knees) in a solid, athletic position. Try not to bounce or wobble at all and use your core to stay solid. Do 8 reps.

Nothing beats planks when it comes to strengthening your deepest abdominal muscles, which flatten out the stomach. Plus, the row builds strength and definition in upper back, shoulders, biceps, and triceps.

How to do it: Grab a set of dumbbells and come into plank position with your feet slightly wider than hip-width apart. Brace your core as you lift one dumbbell off the ground in a rowing movement. Bring the weight back to the ground and switch sides. Continue alternating at a quick pace. Make sure to keep hips as still as possible and legs engaged the entire time. Do 8 reps per side.

Jumping rope is a quick way to get the benefits of cardio without spending a lot of time on it.

How to do it: Make sure to stay light on your feet and keep your chest lifted. Use your wrists more than your arms to swing the rope. Try to keep elbows fixed in place. Jump rope for 1 minute.

This exercise builds strength in the quadriceps, core, glutes, and upper body. Doing single-leg exercises like this improves balance and stability, as well as dynamic flexibility in the knee, ankle, and hip joints.

How to do it: Grab a pair of dumbbells and stand tall, holding the weights by your sides. Take a big step out into a lunge. Bend both knees, keeping front knee directly above ankle. Drive off the ball of your big toe to come up in a standing position. Keep your foot off the ground as you curl the dumbbells up toward your shoulders. Keep elbows fixed in place. Continue by stepping the foot that is lifted forward into a lunge. Do 10 reps on each leg.

Sprints are a very efficient way to improve athletic performance and keep the entire body lean and strong.

How to do it: Start in a lunge position with your back at a 45-degree angle, weight shifted forward. Drive through your big toe to take bounding steps forward. After about 10 yards, rest for 30 seconds before starting your next sprint. Quickly shift your hips forward to repeat the forward movement again. Do 5 sprints.
