Steady-State (Continuous) Training

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 aerobic-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).

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).
• Moderate-intensity continuous training (MICT) — the classic moderate aerobic session (see mict).
• 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. Per ACSM and the major public-health guidelines, most weekly aerobic volume for general health is accumulated through moderate continuous training (see cardiorespiratory-guidelines and weekly-aerobic-volume).

• 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 default vehicle for accumulating weekly aerobic minutes for general health.

• mict — the moderate-intensity version, the public-health default.
• liss — the low-intensity version.
• long-slow-distance — the high-volume endurance application.
• zone-2-training — steady state held just below the first lactate threshold.
• interval-training — the contrasting oscillating-intensity approach.
• cardiorespiratory-guidelines — the guideline side this method delivers.
• aerobic-system — the energy system it develops.
