Sustained aerobic exercise held at a constant, submaximal intensity for an extended block of time — the backbone method of cardiorespiratory training.
Detail
Continuous (steady-state) training means moving at one roughly unchanging intensity for the whole session, with no programmed work/rest swings. The metabolic demand is met predominantly by the Oxygen (Aerobic) Energy System, so the effort can be maintained for many minutes to hours depending on how hard the pace is.
The defining feature is a stable physiological "steady state": after a few minutes the oxygen uptake rises to match the energy cost of the activity and then plateaus, so heart rate, ventilation, and fuel use settle at a constant level. This is the opposite of interval training, where intensity deliberately oscillates above and below the steady state (see Interval Training (General)).
Continuous training spans a wide intensity range, and the sub-methods are named by where they sit on that range:
- Low-intensity steady state (LISS) — easy, conversational effort (see LISS (Low-Intensity Steady State)).
- Moderate-intensity continuous training (MICT) — the classic moderate aerobic session (see MICT (Moderate-Intensity Continuous Training)).
- Tempo/threshold continuous work — sustained effort near the lactate/ventilatory threshold (see Tempo / Threshold Training).
Because the intensity is constant, prescription is simple: pick an intensity zone (by heart rate, RPE, pace, or power), pick a duration, and hold it. ACSM's 2011 position stand and the U.S. Physical Activity Guidelines (2018) set the weekly dose in moderate and/or vigorous minutes and let it be done in one continuous session or in several shorter bouts; ACSM also notes interval training can be effective. Steady moderate work is simply the most common, easiest-to-sustain way to accumulate those minutes (see Cardiorespiratory Conditioning Guidelines (Peterson & Bryant / ACSM) and Weekly Aerobic Volume Targets).
Key facts
- Constant submaximal intensity held continuously; relies mainly on the aerobic system.
- Oxygen uptake plateaus to match energy cost — a true "steady state" — typically within 2–3 min.
- Intensity sub-types: LISS (light), MICT (moderate), tempo/threshold (hard but sustainable).
- Contrast with interval training, which alternates work and recovery bouts.
- The most common way to accumulate weekly aerobic minutes; guidelines also accept intervals and short bouts.
Connections
- MICT (Moderate-Intensity Continuous Training) — the moderate-intensity version, the public-health default.
- LISS (Low-Intensity Steady State) — the low-intensity version.
- Long Slow Distance (LSD) — the high-volume endurance application.
- Zone 2 Training — steady state held just below the first lactate threshold.
- Interval Training (General) — the contrasting oscillating-intensity approach.
- Cardiorespiratory Conditioning Guidelines (Peterson & Bryant / ACSM) — the guideline side this method delivers.
- Oxygen (Aerobic) Energy System — the energy system it develops.

Corrections (1)
- 2026-10-13 — Rewrote an unsupported attribution: neither ACSM nor the U.S. guidelines say most weekly aerobic volume should come from moderate continuous training. Both set the weekly dose in moderate and/or vigorous minutes (ACSM 2011: 150 min/week moderate or 75 min/week vigorous; PAGA 2018: 150–300 / 75–150) and allow it in one continuous session or several shorter bouts; ACSM also notes interval training can be effective. Steady moderate work is simply the most common way to accumulate those minutes. Replaced the unread GETP 11th-edition citation with the 2011 position stand.
