Similarly, not every PT or coach is into achieving results for their clients as they are in reaching a certain monetary gain for themselves. So to be fair, there are always two sides to each coin and it pays for the coach/PT to realise that had his client had the proper motivation, he would not have come to get help in the first place. So yes, motivating your client should be paramount on your list first and foremost before hoping/wishing/expecting any program you device to yield an iota of positive result.
Fadi.
