How to start running properly (Coach Genie)

Wear lightweight, soft, sweat-wicking clothes that don’t chafe. Use tights or shorts if you get inner-thigh chafing.
Invest in a proper pair of running shoes — old sneakers often have worn cushioning and increase injury risk.
Use a GPS watch for detailed data, or a phone app with GPS if a watch is too expensive.
Basic accessories: comfortable, non-restrictive outfit and footwear are the priorities.

Track field (400 m per lap, lane 1): great for pace control (easy to check 100 m / 200 m splits) and gentler on joints — ideal for beginners.
Scenic routes (rivers, parks — e.g., Han River): changing scenery helps time pass and keeps motivation up.

Arm swing: keep elbows at about 90°, push arms back rather than forward, keep swings small to conserve energy, and relax your shoulders.
Foot strike:
- Heel strike: often comfortable but has longer ground contact and higher impact.
- Midfoot strike: shorter ground contact and can be faster, but may stress calves/ankles.
- Forefoot: primarily for sprinting — don’t force a change to this for distance running.
Don’t stomp; land lightly and relaxed.
Stride length: run at a comfortable stride and avoid overstriding. (As a rough example, for 160 cm height a stride of ~90–110 cm is a guideline.) Stride will naturally lengthen with speed.
Build ankle strength and flexibility before attempting to change foot strike.

Breathe through both nose and mouth simultaneously (mouth slightly open) to meet higher oxygen demand.
Keep your chin tucked (avoid lifting it) to keep airways open; take deep breaths rather than shallow ones.
If breathing becomes difficult, slow down — train to run at a pace where you can breathe steadily.

Start with easy jogging at a conversational pace (Zone 2) — you should be able to talk while running.
Set time goals first, not distance or pace. Example beginner progression:
1. Start with 10 minutes non-stop.
2. Progress to 20 minutes.
3. Then 30 minutes.
4. Build to 40 minutes of continuous running.
Once you can run 40 minutes comfortably, switch or add distance goals (for example: 3 km → 5 km → 6–7 km).
Frequency: 2–3 times per week for beginners. A common pattern is: run one day, rest one day.
For performance improvement: vary sessions and include recovery days (alternate shorter and longer runs rather than doing the same distance every day).

Rest days are important for recovery and adaptation.
Check your morning resting heart rate to gauge recovery/condition — a higher-than-usual resting HR can indicate poor recovery or illness.
Warm up with dynamic exercises before runs and cool down afterwards. Prioritize post-run static stretching.
For hot weather or joint pain: cool down quickly; apply cold water or ice to sore joints if needed.

Don’t start by running too fast — building endurance slowly prevents burnout and injury.
Don’t abruptly switch foot strike patterns without gradual strength/flexibility work.
Relax while running to reduce shoulder and neck tension and prevent soreness.

Tip: Train at a pace where you can maintain conversation — it helps keep intensity appropriate for building aerobic fitness.
