Pulsing Lunge
This movement can be performed for a multitude of exercises, with the main key to keep the movements smooth and small for both the lowering and raising phase.
For best results work through the middle / lower phase of the exercise, aiming to take your thigh parallel to the floor, then raise a few inches upwards.
Throughout the movement your back should be straight, hips and head facing forward, with the knee of the front leg inline with your ankle joint, never extending past your toes.
Take care when finishing your pulsing movements for the quads, especially if you have been low down for a while, as the contraction of the muscles, will reduce the blood flow to your brain, and can cause you to feel dizzy or light headed for a few seconds.
If you feel dizzy, stop what you’re doing, and aim to sit or lie down straight away, shaking your legs to aid blood flow.
The exercise can be made harder by using either a step box or even Bosu to raise either the front or rear foot when performing the movement.
Additionally you may decide to progress this exercise further by performing some simple arm exercises as you pulse up and down - such as biceps curls.
