When offering circuits to personal training clients in Abu Dhabi this will be very unique to their needs and capabilities. However the beauty of circuits is that all exercises and movements have up to three or four scaling options. Depending on the clients current fitness level, injury situation and experience, we will then choose the exercises that best suit them in order to work towards continuously improving performance, this can be done with a progression or regression movement.
Personally I would always start with a client assessment of squats, push ups, sit ups, and the plank. This allows me to see their current performance levels in balance and co-ordination, general movement and particular their core strength. Depending on the outcome of the assessment I would then design a circuit best suited for my client.
