Key ideas in Building Physical Fitness
- Nearly every gym exercise is a variation of five basic movements: squat, hinge, push, pull, and carry
- A deadlift works the hinge pattern, bending at the hips rather than sitting down
- A farmer's walk tests the carry pattern by moving under load while keeping the body upright
- A hip hinge pushes the hips back with minimal forward knee travel, keeping shins mostly upright
- A squat drops the hips down between the knees with significant knee bend and forward travel
- Hinging loads the glutes and hamstrings on the back of the legs rather than the front thighs
- Doing too much pushing (like bench press) pulls the shoulders forward into a rounded posture
- Pulling exercises (like rows) strengthen the upper back to hold shoulders back and create space in the joint
- Balancing push and pull volume prevents shoulder pinch and wear over time
- Carrying weight, especially on one side, forces the core muscles to resist bending and twisting
- Real core stability means keeping the spine solid and still while the legs and arms move
- Controlling your own body through a full, comfortable range of motion comes first
- Adding light load to a proven pattern comes before heavy loading
- Loading a movement before achieving clean mechanics risks joint strain and reinforces bad habits
- Aerobic base training occurs at a pace where you can hold a steady, full-sentence conversation
- If you can only speak in short, fragmented bursts, your body has crossed into higher-intensity anaerobic work
