I’ve read that interval training can boost cardiovascular performance. In boxing, both endurance and explosive power are crucial. What intervals (duration, rest, intensity) do experienced boxers generally recommend for improving endurance without sacrificing speed? Are there differences between traditional long runs and high-intensity intervals in terms of boxing technique? How do you fit these sessions into your weekly routine?
How does interval training affect endurance in boxing?

I’ve been using targeted interval training for a few years now to maintain both my endurance as a boxer and my speed. For me, the best approach is 4x3-minute intervals on the rowing machine or treadmill: 30 seconds at max intensity (around 90-95% HRmax), followed by 90 seconds of easy rolling or light jogging as active recovery. Between sets, I take a longer break of 2-3 minutes to stabilize my breathing. Alternatively, I also do 6 rounds of 200m sprints (about 20-25 seconds) with 40-second walking breaks. These short, high-intensity bursts train my anaerobic capacity, which is crucial for fast combinations and explosiveness in the ring, while the breaks keep my heart rate from dropping too much and maintain my cardiovascular base.
Compared to long steady-state runs (like 30-45 minutes at a moderate pace), HIIT improves oxygen uptake much faster and has less impact on mobility and reaction speed, both of which are key in boxing. I still incorporate long runs once or twice a week, though—usually on Sunday mornings—to support fat burning and recovery. My typical weekly structure looks like this: Monday – 4x3-minute intervals on the rower, Tuesday – light technical and sparring training, Wednesday – 30-minute easy-paced run, Thursday – 6 rounds of sprints + boxing drills, Friday – active recovery (yoga/stretching), Saturday – sparring + short HIIT session (e.g., 3x1-minute burpees), and Sunday – long run or bike ride. This keeps my endurance high without sacrificing power or boxing technique.
