If you have never been to a circuit style class before, these pointers might highlight why you should give it a go. Note – they might not be called circuits anymore but HIIT, Bootcamp or Tabata all have the same thing in common – they are effectively a circuit.
It’s a great way to train – you can get through lots of exercises – strength and cardio – in a set amount of time, just set a timer for each station (and rest) and you’re good to go. To do a lot of strength work you may need to add in weights, but to get started just use your own body, keep it simple and you’ll get a good workout.
