Knee Raises
This exercise can be performed
either seated or standing, and is good for both your quadriceps muscles, and
also those of your hip flexors, the muscles that connect from your spine and
pelvis onto the top of your thighbone.

Standing or sitting upright
with your back straight, smoothly raise one leg up so that your thigh is parallel
to the floor, holding for 5 – 8 seconds prior to returning back to the ground
and repeating, ideally on the same side (harder) or alternating your legs.
For those that perform this
exercise in a seated position, you may decide to make the exercise harder
by aiming to lift with a straight leg.
For those that are standing,
you may decide to increase the exercise by lifting one leg so that the thigh
is parallel whilst simultaneously bending the other leg, keeping your back
straight throughout, with your arms out by your sides for balance.
