Why do this sort of class?

The fancy names for this sort of training are Metabolic Resistance Training (MTR) or High Intensity Interval Training [ HITT}. I generally just refer to this sort of training as interval or circuit classes.

MTR is circuit training using some sort of weight resistance in grouped sets of exercises with short rest periods. This method of training generates a high metabolic effect during and after your exercise. In low intensity exercise fat oxidation occurs while exercising and stops almost immediately upon completion. During MTR high intensity exercise your body utilises carbs for energy. Then for a long time afterwards [up to 48 hours] fat oxidation takes place as many body systems return to normal. MTR/ interval classes build muscle mass, but as I have already said you will not build huge bulky muscles. The more muscle mass you have the more calories you will burn during and after exercise.

MTR leads the way for burning calories during exercise. The hierarchy for burning calories during exercise is as follows:

  • MTR...circuits with weights.
  • High intensity interval training.... such as sprints followed by a rest period.
  • Aerobic interval training.
  • Steady state cardio.
  • Incidental exercise.
How are these classes run?
  • 10 minutes warm up using exercise machines.
  • 40 minutes interval training run as a circuit.
  • 10 minutes stretching.

What sorts of exercises will I do during the circuits?

Resistance training using free weights, weight machines, resistance bands, your own body weight, Swiss balls, medicine balls, a bosu ball and balance boards. These exercises change frequently from class to class, ensuring you don't get bored and that your body is constantly being challenged. The actual exercises will target multiple muscle groups including your core.

How quickly could I expect to see changes in my body composition?

It depends on your commitment. If you did three interval classes a week and followed my dietary advice you will see changes quickly.


Will women doing this sort of training build big bulky muscles?

Women do not produce enough testosterone to build big muscles. Interval classes will tone you. If women do not do some sort of resistance training, over time they lose muscle mass. This lowers their metabolism which makes staying lean difficult.

How many people will be in each interval class?

Only five or six. This means I can stand beside you as you execute a new exercise, correct your technique if needed and above all ensure you are performing the exercise safely. The small class size means I am able to cater for your individual needs and offer alternative exercises when necessary. I am able to form a relationship with you. You will be getting many of the benefits of a personal trainer for a substantially reduced price

Small class size does mean booking is essential.


Is this class suitable for me?

This sort of class is suitable for many people, from the very fit,  to people just starting an exercise program. I can cater for you if you have an injury eg a  sore knee or a sore shoulder however you do need to be realistic. If you have quite a few aches and pains you will be  better off with one on one personal training because you will require a very special program to cater for your very specific needs.
