To do bicycle crunches, do the following:
- Lie on your back with your hands behind your head and your feet raised. Your knees should be bent to 90 degrees.
- Start the movement by bringing your right elbow towards your left knee and straightening—pushing the pedal—with your right leg.
- Hold for one second, then alternate to the other leg-elbow combination.
- Continue alternating between the left and right sides for 15 repetitions per side.
2. Heel Grabber Waist Exercise

Here’s how to complete this exercise:
- Lie on your back with your feet flat on the ground and your arms by your sides.
- Crunch up by raising your chest towards the ceiling. Engage your abs.
- Reach for your right heel with your right hand by gently sliding it. Then reach for your left heel with your left hand. Keep your abs engaged throughout the movements, and avoid leaning up.
- Continue alternating right- and left-side reaches for 15 repetitions per side.
3. V-Ups and Knee Hugs

V-ups and knee hugs can be done as follows:
- Lie on your back with your legs straight and your arms over your head.
- Move both arms and legs towards each other so they meet above your waist.
- Squeeze your abs as you slowly lower down to the floor in a controlled movement.
- Repeat for a total of 15 repetitions.
You can try knee hugs if this is too difficult. For this variation, do the same movement, except with bent knees.

Why Do You Need a Strong Core?
You can’t “tighten” your core, so to speak, but you can engage and strengthen it.
The core is the group of muscles that surround the spine in the trunk and hip regions. Engaging your core means you prevent undue movement along your spine and pelvis while working your core against a force like a weight you’re lifting (or gravity if you’re doing a sit-up).
Having a strong core can help prevent lower back injuries.4 Training your core can also improve your balance and stability.
Tips for Effective Waist Workouts
Remember the following tips if you decide to do a waist workout:
- Choose an effective workout that’s also low-risk and enjoyable.
- Combine high-rep bodyweight core exercises with some resistance, like using dumbbells when possible.
- Use a variety of movements to target different muscles.
What Should You Eat for a Lean Core
Core exercises are only part of the equation for a stronger core; what you eat plays a role, too.
To help you build muscle in general, try adding more of these foods into your diet:
- Complex carbohydrates—like legumes, rice, and starchy vegetables
- Fruits and vegetables
