Looking for a way to build aerobic power? Here’s what stood out in The Running Channel’s guide to improving your VO2 max. The full video is worth watching. This breakdown lets you get started with a session right away.

Key points

• VO2 max measures the oxygen your body consumes per kilogram of weight each minute. Higher numbers mean your aerobic engine can handle sustained intensity.
• Lab testing gives exact figures, but smartwatches offer a practical alternative. They estimate your VO2 max once you’ve logged enough running data.
• The fastest gains come from high-intensity interval training that keeps an elevated average heart rate across 15-20 minutes of hard work.
• Run intervals right at your VO2-max pace, the effort you’d sustain for about 5-10 minutes (typically your 1-mile race speed for most runners).
• During recovery, keep jogging lightly. Don’t let your heart rate drift too low.

Workout example

Pick one that fits your fitness level:

1. Short-interval option: 30 seconds hard at VO2-max pace, 30 seconds easy jog, repeat 15 times (about 15 min hard effort).
2. Medium-interval option: 60 seconds hard, 45 seconds easy jog, repeat 10-12 times (about 12-15 min hard effort).
3. Traditional VO2-max interval: 2-minute hard effort at VO2-max pace, 2-minute jog recovery, start with 4 repeats and build up to 8-10 repeats (about 16-20 min hard effort).
4. Hill version: 2-minute uphill run at VO2-max effort (moderate grade), jog back down for recovery, repeat 8-10 times.

Practical tips

• Find your VO2-max pace by identifying the fastest effort you can sustain for 5-10 minutes. Use that to set your interval targets.
• A smartwatch is your tool for monitoring heart rate and pace, and it’ll estimate your VO2 max as patterns emerge over time.
• Record workouts in the Pacing app to track where you started and fine-tune your paces as your fitness climbs.
• Balance these sessions with easier runs, long runs, and threshold work elsewhere in the week to avoid burnout.

Closing note

Pick one of these workouts for this week, dial in the paces to your current shape, and watch your aerobic capacity improve. Log it with the Pacing app and keep showing up.
