puzzle fitness

3. training – Moves through several exercises in a sequence with minimal rest to improve fitness.
4. – Loss or shrinking of muscle from lack of use.
5. strength – Builds the ability of muscles to exert maximum force (lifting heavy weight).
8. exercise – Strengthens muscles through movement (muscle changes length, like lifting weights).
10. strength – Strengthens muscles in your abdomen and lower back for stability and balance.
11. weights – Uses equipment like dumbbells and barbells to build strength and coordination.
12. exercise – Builds strength without movement (holding a position, like a plank).
13. interval – The time you rest between sets or exercises to recover.
14. contraction – Muscle shortens as it contracts (lifting a weight).
15. overload – Gradually increasing weight, reps, or intensity to keep improving.
17. weights – Use gym machines to guide movement and target specific muscles safely.
18. – Doing two exercises back-to-back with little or no rest to save time and increase intensity.
19. training – Builds strength by working against resistance (weights, bands, bodyweight).

1. exercises – Use your own body for resistance (push-ups, squats).
2. contraction – Muscle lengthens under tension (lowering a weight slowly).
6. (rep) – One complete movement of an exercise (like one push-up).
7. – Increases muscle size (muscle growth from training).
9. max (1RM) – The maximum weight you can lift for one repetition.
16. – A group of repetitions done in a row before resting.
17. endurance – Improves how long muscles can keep working without getting tired.
