The Pendulum Leg Plus is a dynamic plank variation that challenges lateral core stability and shoulder endurance while engaging the lower body. It effectively targets the obliques and serratus anterior through a combination of a lateral leg swing and a focused knee-to-elbow crunch.

Setup
- Start in a high plank position with your hands placed directly under your shoulders and feet hip-width apart.
- Engage your core, squeeze your glutes, and ensure your body forms a straight line from head to heels.
- Press firmly through your palms to protract your shoulder blades, creating a strong 'plus' position in the upper back.
How to do it
- Keeping your leg straight, swing one leg out to the side in a wide arc (the pendulum) while keeping your hips level with the floor.
- From the lateral position, bend your knee and drive it toward the outside of the same-side elbow, exhaling as you crunch your obliques.
- Inhale as you reverse the movement, extending the leg back out and returning it to the starting plank position.
- Alternate sides for each repetition, maintaining a controlled 2-1-2 tempo (2 seconds out, 1 second crunch, 2 seconds back).
Form checklist
- Keep your hips square to the ground; do not let them rotate as the leg swings.
- Maintain a strong 'push' through the floor to keep the chest and shoulders active.
- Avoid letting your lower back arch or your hips sag toward the floor.
- Keep your neck neutral by looking at a point about 6 inches in front of your hands.
Pro tips
- To maximize oblique engagement, try to actually touch your knee to your triceps during the 'plus' phase.
- Focus on keeping the moving leg parallel to the floor throughout the pendulum swing to increase hip and quad tension.
Make it harder
- Perform a push-up between each alternating leg cycle to increase pectoral and tricep demand.
- Slow down the lateral swing to a 4-second count to significantly increase the stability requirement for the standing leg and core.
Frequently asked
- What muscles does the pendulum leg plus work?
- The pendulum leg plus primarily targets the glutes, hamstrings, and quadriceps, and also works the adductors and hip flexors as secondary muscles.
- What equipment do you need for the pendulum leg plus?
- The pendulum leg plus requires no equipment — just your body weight.
- Is the pendulum leg plus good for beginners?
- The pendulum leg plus is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
