Here's the thing: It doesn't matter if you're a bikini and crop top kinda gal or love your trendy one-pieces and cozy sweaters. Everyone needs strong abs. (Seriously, they're really important muscles, and not just for show.)
You don't need to dedicate hours to burning out your core muscles, though. This 10-minute abs blast from Karena Dawn and Katrina Scott, the leading ladies of Tone It Up, will do just the trick. They picked their five favorite core-sculpting moves from their upcoming 2018 Bikini Series fitness challenge and created this 10-minute abs routine that you can tack on to the end of your routine twice a week. (If you want more, you can sign up for the full eight-week challenge in their Studio Tone It Up app or check out the 30-Day Tone It Up x Shape Weight-Loss Challenge.)
How it works: Repeat this routine 3 times total. Try it twice a week, and watch your core get crazy strong.
Total Time: up to 15 minutes
1. Mermaid Crunches
Lie on your left side with left elbow on the ground, supporting upper body with right hand behind head. Lift legs about a foot off the ground to balance on left hip to start.
Keeping feet together, engage right obliques to draw the knees and right elbow together over torso. Extend legs to return to starting position.
15 per side
2. Toe Touches
Lie faceup on the ground with legs extended toward the sky and hands reaching toward feet to start.
With core engaged, reach hands to touch toes, lifting shoulder blades off the ground. With control, lower shoulders back to the ground to return to starting position.
3. Rock the Boat
Start in boat pose, balancing on tailbone with feet in the air, knees bent and shins parallel to the floor. Hold a single dumbbell horizontally with both hands in front of chest.
Engage core to twist torso to the right, lowering dumbbell toward the right hip. Repeat on the left side.
15 per side
Resist the urge to tilt hips side to side. Only the upper body should move.
4. Starfish Crunch
Lie faceup on the ground with arms and legs extended, creating an "X" position.
In one movement, lift arms, shoulders, and legs off the ground, hugging knees to chest. Slowly lower back down to return to starting position.
If possible, keep feet off the ground in between reps.
5. Plank Hip Dip
Start in a low plank position with shoulders directly over elbows.
Keeping core engaged, rotate hips to the right, lowering right hip close to the floor. Return to center, then repeat on the other side.
15 per side
Don't allow the lower back to extend/arch.
