Instructions for Proper Form
Vertical Knee Raise is a bodyweight core exercise that involves suspending yourself, and then engaging your core to raise your knees towards your chest. By keeping your torso upright, and raising your knees, this exercise is a bit better for building functional, real world strength.
- Stand upright on the pedals of a vertical leg raise bench.
- Press your back against the pad and rest your forearms on the parallel bars grabbing a hold of the handles with your palms facing in.
- Brace your core to keep your head extended away from your shoulders before suspending your body above the floor.
- Avoid any swinging as you flex your hips and your abdomen to bring your knees up to your chest.
- Lower your legs to the extended position.
Common Form Mistakes
Resting Between Reps
Keep your core engaged for the duration of the exercise, even between reps. This exercise is designed to add instability that your core needs to compensate for. Keeping your core engaged throughout the exercise will improve the effectiveness of the exercise.

2. Crunches
94 mSCORESWAPPED 4,077 TIMESCrunches are one of the most common exercises out there. It’s an easy to perform, bodyweight exercise that targets your abdominals. Crunches are very similar to Sit Ups, however, instead of raising your upper body all the way into a near sitting position, you only raise your shoulder blades off the ground. This is a great exercise for beginners looking to build core strength.
3. Bicycle Crunch
91.8 mSCORESWAPPED 3,794 TIMESBicycle Crunch is a more difficult version of a standard crunch. Instead of raising your torso off the ground for each rep, you keep your torso off the ground, and your core engaged. By cycling your legs, you add more instability to the movement, which leads to better core activation.
4. Leg Raise
96.5 mSCORESWAPPED 3,560 TIMESLeg Raise is a simple bodyweight core exercise that involves laying on the ground and suspending your legs in the air. While your core does play a significant role in raising your legs, the real benefit comes from controlling their descent back to the floor.
5. Plank
92.8 mSCORESWAPPED 3,300 TIMESPlanks are one of the most common core exercises out there. This is a bodyweight exercise that is performed for time rather than reps. Planks don’t require any movement, instead they force you to place yourself in a position that requires you to engage your core, and maintain that muscle activation for the duration of the exercise. This is a great way to help build strength and stability in a way that will translate to a variety of other exercises, and your daily life.
6. Leg Pull-In
94.9 mSCORESWAPPED 2,631 TIMESLeg Pull in is a bodyweight exercise that targets your core. By raising your legs off the ground, you’re already engaging your core. Additionally your core helps to pull your legs in towards your chest.
7. Vertical Leg Raise
82.2 mSCORESWAPPED 2,526 TIMESVertical Leg Raise is a more challenging variation of Vertical Knee Raise. By keeping your legs straight as you raise them up and away from you, you add significantly more resistance to this exercise. Keeping your legs extended also forces you to engage your quadriceps. This is a great variation for anyone looking to make their Vertical Knee Raises more challenging.

8. Russian Twist
