1. **Plank**: A core strength exercise where you hold a position similar to a push-up, with your body straight and supported by your forearms and toes.

2. **Core strength**: The ability of the muscles in the torso to stabilize the spine and pelvis, crucial for overall stability and movement efficiency.

3. **Physical benefits**: The positive effects on the body resulting from physical activity, such as improved strength, flexibility, endurance, and overall health.

4. **Isotonic**: Muscle contraction where the muscle length changes, such as during traditional weightlifting exercises where the muscle shortens and lengthens.

5. **Isometric**: Muscle contraction where the muscle length stays the same, such as holding a static position like a plank.

6. **Plyometric moves**: Exercises that involve quick, explosive movements to develop power and speed, often involving jumping or throwing.

7. **Reverse lunge**: A variation of the lunge exercise where you step backward instead of forward, engaging different muscles in the legs and hips.

8. **90° degrees**: A measurement of angle, often used in exercises to indicate a right angle, such as in knee or elbow bends.

9. **Muscular strength**: The maximum amount of force a muscle or group of muscles can generate in a single effort.

10. **Hamstrings**: Muscles located on the back of the thigh, responsible for bending the knee and extending the hip.

11. **Endurance**: The ability of muscles to perform repeated contractions over an extended period without fatigue.

12. **180° degrees**: A measurement of angle, indicating a half-circle or straight line.

13. **Lateral lunge**: A variation of the lunge exercise where you step to the side instead of forward or backward, targeting different muscles in the legs and hips.

14. **Curtsy lunge**: A variation of the lunge exercise where you step one leg diagonally behind the other, mimicking the motion of a curtsy.

15. **Pectorals**: Muscles of the chest responsible for movements such as pushing and hugging.

16. **Deltoids**: Muscles of the shoulder responsible for shoulder abduction, flexion, and extension.

17. **Triceps**: Muscles on the back of the upper arm responsible for extending the elbow joint.

18. **Rectus abdominis**: A paired muscle running vertically on each side of the anterior wall of the human abdomen, commonly known as the "abs."

19. **Abdominis**: Short for rectus abdominis, the abdominal muscles.

20. **Gluteus medius**: A muscle located on the outer surface of the pelvis, responsible for hip abduction and stabilization.

21. **Side lunge**: A variation of the lunge exercise where you step to the side, engaging different muscles in the legs and hips compared to a forward or backward lunge.

22. **Cellulite**: A condition characterized by a dimpled, lumpy appearance of the skin, often found on the thighs, buttocks, and hips, typically more common in women. It's not directly related to exercise but can be influenced by factors such as genetics, lifestyle, and body composition.
