Press start and the timer calls each station and rest, and buzzes on phones that allow it. Moderate effort means you can still talk in short sentences; vigorous means a few words at most.
Chest pain, dizziness or unusual breathlessness: stop, and call 999 if it does not pass.
The working
8 stations, 40 on and 20 off, 3 rounds
Each round is 8 × 40 seconds plus 7 rests of 20 = 7:40. Three rounds with two 60 second breaks make 25 minutes. At moderate effort (5 METs) and 11 st that is about 146 kcal.
Picking stations
Mix it up
- Alternate legs, upper body and core
- Put the hardest move early
- Have an easier version of every station
- Water and a towel within reach
Effort
METs from the Compendium
In the 2024 Compendium, moderate circuit training is 5 METs and circuits with minimal rest are 7.5. One MET is about 1 kcal per kg of body weight per hour.
The timer
Each station called for you
Press start the circuit and the page runs every station, rest and round rest in order, naming each one as it comes up, so you can put the phone down and work. It reads the changes out to screen readers and buzzes on phones that allow it. Keep the screen on while it runs.
