Instructions
All Fours Quad Stretch
Start off on your hands and knees, then lift your leg off the floor and hold the foot with your hand.
Use your hand to hold the foot or ankle, keeping the knee fully flexed, stretching the quadriceps and hip flexors.
Focus on extending your hips, thrusting them towards the floor. Hold for 10-20 seconds and then switch sides.
Leg Extensions
For this exercise you will need to use a leg extension machine. First choose your weight and sit on the machine with your legs under the pad (feet pointed forward) and the hands holding the side bars. This will be your starting position. Tip: You will need to adjust the pad so that it falls on top of your lower leg (just above your feet). Also, make sure that your legs form a 90-degree angle between the lower and upper leg. If the angle is less than 90-degrees then that means the knee is over the toes which in turn creates undue stress at the knee joint. If the machine is designed that way, either look for another machine or just make sure that when you start executing the exercise you stop going down once you hit the 90-degree angle.
Using your quadriceps, extend your legs to the maximum as you exhale. Ensure that the rest of the body remains stationary on the seat. Pause a second on the contracted position.
Slowly lower the weight back to the original position as you inhale, ensuring that you do not go past the 90-degree angle limit.
Repeat for the recommended amount of times.
Verdict
Both exercises target the quadriceps. All Fours Quad Stretch is a intermediate exercise using bodyweight, while Leg Extensions is beginner and uses machine. Choose Leg Extensions if you're looking for a more accessible option, or All Fours Quad Stretch for a greater challenge.
