Best match 
1. Standing Long Jump
40% match- Quadriceps
- Bodyweight
- Advanced
- Compound
Use this when you have nothing to train with, because it works the quadriceps with bodyweight alone.
How to perform this exercise
- This drill is best done in sand or other soft landing surface. Ensure that you are able to measure distance. Stand in a partial squat stance with feet shoulder width apart.
- Utilizing a big arm swing and a countermovement of the legs, jump forward as far as you can.
- Attempt to land with your feet out in front you, reaching as far as possible with your legs.
- Measure the distance from your landing point to the starting point and track results.
Sets and reps: 3 or 4 sets of 6 to 10 reps.
Why this matches
- Primary muscle: quadriceps, the same as the Single-leg Leg Extension

2. Single Leg Butt Kick
40% match- Quadriceps

- Immediately flex the knee and attempt to touch your butt with the heel of your jumping leg.
- Return the leg to a partially bent position underneath the hips and land. Your opposite leg should stay in relatively the same position throughout the drill.

3. Glute Kickback
40% match- Glutes
- Bodyweight
- Beginner
- Isolation
A looser match: it works the glutes rather than the quadriceps.
How to perform this exercise
- Kneel on the floor or an exercise mat and bend at the waist with your arms extended in front of you (perpendicular to the torso) in order to get into a kneeling push-up position but with the arms spaced at shoulder width. Your head should be looking forward and the bend of the knees should create a 90-degree angle between the hamstrings and the calves. This will be your starting position.
- As you exhale, lift up your right leg until the hamstrings are in line with the back while maintaining the 90-degree angle bend. Contract the glutes throughout this movement and hold the contraction at the top for a second. Tip: At the end of the movement the upper leg should be parallel to the floor while the calf should be perpendicular to it.
- Go back to the initial position as you inhale and now repeat with the left leg.
- Continue to alternate legs until all of the recommended repetitions have been performed.
Sets and reps: 3 sets of 8 to 12 reps on each side, and add reps before you add load.
