ACSM's prescription template — Frequency, Intensity, Time, Type, plus Volume and Progression — used to build a complete, individualized aerobic exercise plan.
Detail
FITT-VP is ACSM's framework for writing an exercise prescription. The original FITT (Frequency, Intensity, Time, Type) is extended with Volume and Progression:
- Frequency — how often. For aerobic work ACSM recommends ≥5 days/week of moderate-intensity, ≥3 days/week of vigorous-intensity, or 3–5 days/week of a combination.
- Intensity — how hard. Set with the intensity classification (moderate = 40–59% HRR/VO2R, 64–76% HRmax, RPE 12–13; vigorous = ≥60% HRR/VO2R, ≥77% HRmax, RPE ≥14; see intensity-classification).
- Time — how long per session (duration), e.g., enough to accumulate the weekly target.
- Type — the mode: any continuous, rhythmic activity using large muscle groups (walking, running, cycling, swimming, rowing, etc.).
- Volume — the total dose, the product of frequency × intensity × time, often expressed in minutes/week or MET-minutes/week (see weekly-aerobic-volume).
- Progression — how the prescription advances over time, by gradually increasing frequency, intensity, and/or time (see cardio-progression).
FITT-VP is the structural checklist behind the public-health guidelines and the conditioning-domain prescription (see cardiorespiratory-guidelines). It is mode- agnostic — the same template is filled in differently for a beginner walker versus a trained runner — and pairs with a training-intensity-distribution decision (how to split the weekly volume across easy/hard work; see training-intensity-distribution).
Key facts
- FITT-VP = Frequency, Intensity, Time, Type, Volume, Progression.
- ACSM frequency: ≥5 d/wk moderate, ≥3 d/wk vigorous, or 3–5 d/wk combined.
- Intensity set via the moderate/vigorous classification bands.
- Volume = frequency × intensity × time (min/week or MET-min/week).
- Type = continuous, rhythmic, large-muscle activity; mode-agnostic template.

Progressing Cardio TrainingClosely related
Advance aerobic training by gradually raising one variable at a time — usually duration/frequency first, intensity later — in small increments, with the biggest early gains in the first 6–8 weeks.Aerobic Intensity Classification (Light / Moderate / Vigorous)
ACSM's master table for translating "moderate" and "vigorous" into numbers across every common metric — %HRR/VO2R, %HRmax, RPE, and METs.Training-Intensity Distribution (Polarized / Threshold / Pyramidal)
How a week's training time is split across easy, moderate, and hard zones — the main models being polarized (mostly easy + some very hard), threshold (lots of moderate), and pyramidal (a tapering pyramid from easy to hard).Weekly Aerobic Volume Targets
The headline dose from WHO and U.S. guidelines — 150–300 minutes of moderate, or 75–150 minutes of vigorous, aerobic activity per week (or an equivalent mix).Cardiorespiratory Conditioning Guidelines (Peterson & Bryant / ACSM)Closely related
The five-part ACSM prescription for building and keeping cardiorespiratory fitness — frequency 3–5 days/wk, intensity 60–90% of max HR, duration 20–60 min, large-muscle continuous aerobic mode, and gradual progression.Rate of Progression and the Training EffectClosely related
As the body adapts to imposed stress (the training effect), total work can be raised gradually — by more intensity, more duration, or both — with the most significant conditioning gains in the first 6–8 weeks.Frequency of Training
How many days per week you train — don't work the same muscle two days in a row, and generally not more than three times a week.Intensity
The amount of weight (resistance) lifted — also shaped by speed, reps, sets, rest interval, and workout duration.
