How to use the online timer
Sixty seconds at each station followed by fifteen seconds to move to the next, across six stations, is a common circuit training structure that keeps the heart rate elevated through transitions rather than letting it drop while you set up the next exercise. Fifteen seconds is tight on purpose — just enough to reposition, not enough for a proper rest, which is what separates circuit training from a series of isolated exercises done one after another.
Choosing stations that alternate between muscle groups — say, legs, then upper body, then core — keeps any one area from being asked to work flat out twice in a row, which lets you keep intensity higher for longer than if the same muscles were hit back to back.
A full circuit through all six stations is one round; most sessions repeat the whole circuit two or three times with a slightly longer break of a minute or two between rounds. Form matters more here than in steady, single-exercise training, because fatigue builds station by station — if technique starts to break down on a particular exercise, it's better to drop the intensity on that one station than to push through with poor form.
Common questions
Why is fifteen seconds not enough to set up the next station?
That's intentional — it keeps your heart rate elevated through the transition rather than letting it drop, which is part of what separates circuits from isolated exercises.
Should I keep the same order of stations every time?
Alternating muscle groups station to station, rather than repeating the same area back to back, helps maintain intensity across the full circuit.
