VO2 max is the gold standard for measuring how efficiently your body uses oxygen during exercise. If you’re trying to set a personal best, podium at races, or shift your training into the next gear, focusing on improving your VO2 max is key. Here are three workouts designed to help you optimize your aerobic capacity while keeping things (relatively) fun. 

1. Anaerobic Sprints: Short and Sweet

Looking to tap into raw power? Anaerobic sprints are your ticket to greater VO2 max gains. These high-intensity, short-duration efforts push your cardiovascular system to its limits, helping you develop both speed and endurance.

How to Do It: 
- Duration: 20–30 seconds for each sprint  
- Recovery: Rest for 2–3 minutes between sprints  
- Intensity: Aim for a Rate of Perceived Exertion (RPE) of 9–10 (maximum effort). Your heart rate should soar into Zone 5, anywhere from 90% to 100% of your maximum heart rate. 

Example: After a thorough warm-up, sprint at your top speed for 20–30 seconds, then fully recover before your next effort. Aim for 5–8 sprints per session. Super quick and super effective!

2. Hill Repeats: Climbing to Success

Hill repeats are how you build a “bigger engine.”  They provide that sweet burn while challenging your strength and endurance. The incline challenges your cardiovascular system and builds crucial leg power.

How to Do It:  
- Duration: 60–90 seconds climbing up a hill  
- Recovery: Walk or jog back down for recovery  
- Intensity: Push yourself to an RPE of 8–9, aiming for the upper end of Zone 4, where heart rate maintains 80–90% of your maximum.

Example: Find a hill with a consistent gradient. Sprint uphill for 60–90 seconds, and jog back down to recover. Repeat this 6–10 times, and you'll find those climbs getting easier over time. 

3. Sweet Spot Workout: The Best (or Worst) of Both Worlds

Sweet spot training is perfect for endurance athletes wanting to build their aerobic and anaerobic systems simultaneously. It lies in that “goldilocks zone” — not too hard, not too easy; just right for VO2 max improvements while allowing for sustained efforts.

How to Do It:  
- Duration: 20 minutes within the sweet spot  
- Recovery: 5–10 minutes easy pace before and after  
- Intensity: RPE of 7–8, which means staying in Zone 3 to Zone 4, around 75-85% of your maximum heart rate.

Example: After warming up, ride or run at this moderate-hard intensity for 20 minutes, followed by 5–10 minutes of easy effort to recover. This workout will not only sharpen your engine but also improve your endurance for longer races.
