The Gym
CIRCUIT TRAINING AREA
Gym Equipment
Around the perimeter of the room are 12 pieces of strength training equipment, alternating between upper body, abdominal and leg equipment. In the centre there is a bank of steps, stretching the length of the room.

How it operates
There are a series of 6 lights at either end of the area. Each lights up for 20 seconds, one after the other, i.e. it takes one minute to complete the sequence. There is a 30 second interval between the end of a light sequence and the beginning of the next to allow for change over.
The process is as follows

One minute exercising on a piece of equipment 30 seconds rest to change equipment.
One minute exercising on a step
30 seconds rest to change equipment
A Full Circuit
This two and a half minute process is repeated for all twelve pieces of equipment. A full circuit takes 30 minutes because you do 12 pieces of equipment and 12 steps = 24 minutes. You change in between all of these (24 changes) = 6 minutes.

Advantages
This system has the double advantage of providing a full body workout in 30 minutes, and ensuring that there is no waiting time for chosen equipment to become available.
