I cancelled my gym membership 6 months ago and replaced it with this:
Setup: Heavy bag + round timer. That’s it.
The workout (20 min):
- Round 1-2: Shadow boxing warmup (2 min rounds, 30 sec rest)
- Round 3-5: Combo drills on the bag (3 min rounds, 1 min rest)
- Round 6-8: Power rounds — everything you’ve got (2 min rounds, 30 sec rest)
- Round 9: Burnout round — non-stop combos, no pacing (3 min)
- Cooldown: 2 min slow shadow boxing
I’ve lost 15lbs and my resting heart rate is lower than when I was running 5K three times a week.
The key is the timer structure. I use BoxTime because I can set different round lengths within one session. But any timer works — the important thing is not letting yourself rest longer than planned.
Anyone else doing boxing as their primary workout?
