How to Use the RollMassif VO₂max & FTP Calculator (Step-by-Step)

  1. Find your best recent power number
    Do (or use) one of these efforts:
    • 20-minute all-out test (classic FTP test)
    • 5-minute or 8-minute maximal effort
    • Full 60-minute race or “hour of power”
    Take the average power in watts from that effort.

  2. Enter your details
    • Weight → current body weight (riding weight)
    • Power → the average watts from step 1
    • Test duration → choose 5, 8, 20 or 60 minutes
    • Environment → choose “Indoor” if it was on Zwift, Kickr, Tacx, etc.
    • Gender & Age → for accurate ranking and percentile

  3. Click “CALCULATE EVERYTHING”
    In seconds you get:
    • Your exact Watts/kg (the #1 cycling metric)
    • Estimated VO₂max in ml/kg/min
    • Real-world Functional Threshold Power (FTP)
    • What level you ride at (Cat 4 → WorldTour Pro)
    • How you rank against all riders your age & gender

  4. Save or share your result
    • Download a clean image
    • Print or save as PDF (perfect for your coach)
    • Share instantly on X, Strava, WhatsApp, etc.
Pro tip: Do a fresh 20-minute test every 6–8 weeks and come back here — watch your watts/kg climb and see your progress chart grow automatically!

Can I use the VO₂ max calculator for a 20-minute cycling test?


Yes, our calculator can do VO₂ max calculator cycling 20 minutes.

How to improve vo2 max?

Improving VO₂ max requires consistent cardiovascular training that challenges your heart, lungs, and muscles. High-intensity interval training (HIIT) is one of the most effective methods is in short bursts of hard cycling followed by recovery periods drive your body to use oxygen more efficiently. Adding threshold workouts, where you ride just below your maximum sustainable intensity for extended periods, also helps increase aerobic capacity.

Complement your intense sessions with steady-state endurance rides to build a strong aerobic base. Aim for progressive overload by gradually increasing duration, intensity, or frequency. Supporting habits –such as adequate sleep, proper hydration, and balanced nutrition – help your body adapt and improve faster.

What is a good vo2 max by age female?

A good VO₂ max for women varies by age because aerobic capacity naturally declines over time. In general, women in their 20s often have VO₂ max values in the low-to-mid 40s (ml/kg/min) considered average, with anything above the high 40s or 50s viewed as good to excellent. As age increases, these ranges shift downward by a few points per decade.

By the 40s and 50s, average values typically fall into the mid-30s, with good scores moving into the low-to-mid 40s. For women in their 60s and beyond, averages are commonly in the low 30s, while values in the upper 30s and low 40s are considered strong. These ranges help provide context, but individual fitness, genetics, and training habits also play significant roles.

What is vo2 max?

VO₂ max is the maximum amount of oxygen your body can use during intense exercise. It reflects how efficiently your heart, lungs, and muscles work together to deliver and utilize oxygen. Because oxygen is essential for producing energy during sustained activity, VO₂ max is considered one of the best indicators of aerobic fitness.

A higher VO₂ max generally means you can perform harder or longer before fatigue sets in. While genetics play a role, training-especially endurance and high-intensity workouts-can significantly improve your VO₂ max over time.

What is a good vo2 max by age?

A good VO₂ max varies by age because aerobic capacity naturally declines over time. In general, younger adults tend to have higher values, with “good” scores gradually decreasing by a few points per decade. For men, a good VO₂ max in the 20s is often in the high 40s to mid-50s (ml/kg/min), while for women it’s typically in the low- to mid-40s. These ranges slowly shift downward with age-by the 40s, good values are usually in the low- to mid-40s for men and upper-30s for women.

By the time individuals reach their 60s, a good VO₂ max is commonly in the mid-30s for men and low-30s for women. These numbers serve as general benchmarks, but training level, body composition, and genetics also play major roles. Even if your value falls below average for your age, consistent aerobic and interval training can significantly improve your score over time.

vo2 max cycling intervals

VO₂ max cycling intervals are structured high-intensity workouts designed to push your heart and lungs close to their maximum capacity. They typically involve short bursts of very hard effort-usually at 90-100% of your VO₂ max power or heart rate-followed by equal or slightly longer recovery periods. These sessions train your body to take in and use more oxygen, which directly increases your aerobic ceiling.

Common VO₂ max interval formats include:

  • 3–5 minutes hard / 3–5 minutes easy, repeated 3-6 times
  • 30/30s: 30 seconds very hard / 30 seconds easy, repeated 10-20 times
  • 2 minutes hard / 2 minutes easy, repeated 5–8 times

Aim to perform VO₂ max intervals 1-2 times per week, allowing enough recovery between sessions. They are demanding, but when combined with regular endurance rides, they are one of the most effective ways to boost VO₂ max and overall cycling performance.
