15-Minute “Butt & Gut” Blast Workout

Who doesn’t love a sculpted butt and flat abs? Who doesn’t love the feeling of slipping into a pair of skinny jeans or feeling confident in a bikini? I know I do! That’s why I created this “butt & gut” workout to whittle your waistline and perk-up your rear-end. Best of all, this workout is super-fast and equipment-free. All you need is a floor, a timer, and 15 minutes! Let’s get training!

Workout Instructions: Set timer to alternate between 20 and 40 second intervals (starting with 20 seconds). Perform each exercise consecutively. Repeat this circuit 3x.

Exercise 1: Russian Twists

• Sit on a mat
• Lean back (core engaged and back flat) with heels anchored into the floor

• Twist side-to-side, aiming your elbows toward the floor (head in-line with the spine; chin off the chest)
• Repeat for 20 seconds

Exercise 2: Donkey Kicks (Left Leg)

• Get into a table-top position (hands under shoulders; knees under hips; hips facing the floor; head in-line with the spine)
• Extend your leg behind you, foot flexed (pretend you’re a donkey kicking through its stall; think about pushing your heel into the wall behind you)
• Lower the knee back toward the floor (without touching)
• Repeat for 40 seconds

Exercise 3: Reverse Crunch

• Lie on your back
• Place the hands under your bum
• Bring the knees in toward your chest, lifting the butt slightly (try not to use momentum)
• Lower the heels toward the floor (or extend your legs straight for an added challenge)
• Repeat for 20 seconds

Exercise 4: Donkey Kicks (Right Leg)

• Get into a table-top position (hands under shoulders; knees under hips; hips facing the floor; head in-line with the spine)
• Extend your leg behind you, foot flexed (pretend you’re a donkey kicking through its stall; think about pushing your heel into the wall behind you!)

• Place the hands under your bum
• Lift the head and shoulders off the mat (chin off the chest)

Exercise 7: High or Low Plank with Knee Taps

• Begin in a high plank position (hands directly under the shoulders; head in-line with the spine; toes planted into the floor; body in a long, straight line) or a low plank position (elbows on the floor directly under the shoulders; head in-line with the spine; toes planted; body in a straight line)
• Alternate lowering one knee toward the floor and lightly tapping the ground
• Repeat for 20 seconds

Exercise 8: Modified Side Plank (Right Side)

• Lie on your side
• Place your elbow on the floor, directly under the shoulder
• Straighten and extend your top leg, placing the knee of your lower leg into the mat (everything from your head to your toe should be in a straight line, like you’re between two panes of glass)
• Extend your top arm toward the ceiling
• Lift your hips toward the ceiling, engaging the side of your waist (pretend there’s a rope tied around your waist and it’s pulling you upward)
• *Optional* Lift and lower the hips
• Hold for 40 seconds

Exercise 9: Scissors

• Lie on your back
• Place your hands under the bum
• Lift the head and shoulders off the mat (chin off the chest)
