1. Day 5 Summary (Fri) โ
| Day | Time | Main Focus | Key Targets |
|---|---|---|---|
| Day 5 (Fri) | 3:30โ5:30 | ๐ฅ Conditioning Intervals (10s fast / 20s calm) | Explosive bursts, breathing control, quick reset, strong posture |
Goal of the day: build a gas tank that can sprint, recover, and sprint again โ without losing technique. Power is greatโฆ but repeatable power wins fights. ๐
2. Why 10s / 20s Works (Fight Logic) ๐ง
In real fights, you donโt go hard for 3 minutes nonstop. You explode in moments:
- โก flurry, counter, or clinch entry (fast burst)
- ๐ฎโ๐จ breathe, frame, move, reset (controlled calm)
- โก explode again
Thatโs exactly what 10 seconds fast / 20 seconds calm trains: output + recovery + repeat.

11. FAQ โ
What does 10s fast / 20s calm mean?
It means you work explosively for 10 seconds, then stay active and controlled for 20 seconds (breathing + footwork). Repeat this cycle for rounds or sets.
Is Day 5 safe for beginners?
Yes, if you scale it. Keep your 10-second bursts at about 70โ85% and focus on clean posture and breathing during the 20 seconds.
How many rounds should I do?
Beginners: 2โ3 rounds. Intermediate: 3โ4 rounds. Fighters: 4โ5 rounds. Quality matters more than quantity.
Should I keep technique during conditioning?
Absolutely. Day 5 is not just cardio โ itโs fight conditioning. If technique breaks, reduce speed and keep form clean.
What if my knees or shins hurt?
Switch to lower-impact options (shadow hands, fast footwork steps, light knees) and focus on warm-up + recovery. Pain is a warning, not a badge.
