You could either point your toes, do lunges or pull your leg up to your bottom (so you are standing on one leg). x
Quadriceps
The vastus medialis is involved in leg extensions.

By doing leg strengthening exercises like: * Squats * Leg Press * Leg Extensions * Lunges * Hamstring Curls * Calf Raises * etc.
They make you stronger. You still need cardio workouts to help with 'speed'. Try running and leg workouts.
Leg extensions primarily target the quadriceps muscles in the front of the thigh and do not effectively work the glutes. To specifically target the glutes, exercises like squats, lunges, and hip thrusts are more effective.
The joint action in leg extensions is knee extension, where the angle between the thigh and lower leg decreases. The main muscles involved in this action are the quadriceps, specifically the vastus medialis, vastus lateralis, vastus intermedius, and rectus femoris. The movement primarily occurs at the knee joint.

Incorporating glute leg extensions into your workout routine can help strengthen and tone your glute muscles, improve your overall lower body strength, enhance your athletic performance, and reduce the risk of injury.
