One of the most effective and original ways to train the whole body, this has been used since 1953 and is based on a number of exercises being completed in a ‘circuit’ based on either a number of repetitions or a period of time depending on the training need. Utilising resistance equipment such as dumb bells, bar bells, medicine balls, Bulgarian bag’s, kettle bells, TRX etc means that we train both the cardiovascular and muscle endurance within the same work out which improves Vo2 max figures. I adopt various circuit styles including ladders, pyramids, intervals, superset, giant set amongst many others. This class is appropriate for all ages and abilities and we regularly see ladies in their 60’s as well as rugby and football players, police officers, boxers, cyclists, mums and daughters.
