If we skip the aesthetic reasons of having a trainer, that actually exercises themselves, because frankly I do not believe a good coach needs to be shredded in order to be a good coach. I do believe that the benefits of exercise goes beyond that.
As a coach who does train themselves, I know what my clients are going through. I know the games your mind can play on your, when the last thing you want to do is get your butt out of bed and into the gym. I know what it's like to have to psych yourself up just to do one extra rep. How awful it is when you have missed a workout or how great you feel when you reach a personal best. The mental fortitude it takes to stick to a routine, but most of all I know how to make it a part of your life and ultimately to maintain consistency is what it takes to see real results.
Now putting the benefits that exercise provides, regular gym sessions keeps my knowledge on what is trending, what works, what doesn't work, fresh in my mind. I go to classes, I watch and I'm continually learning and researching ways to help my clients get results. If the only time your coach sets foot around exercise is to train you, you can guarantee that the workouts will get stale and their knowledge will be outdated.
So do yourself a favour, next time you are doing a consultation with a Coach or trainer ask THEM a few questions: "how long have you been training clients?" "What kind of fitness do you enjoy?", These simple questions will give you a quick idea if your potential coach has both a passion for fitness as well as the experience to guide you. In an industry where the barrier to entry is so low, it's important that you spend your money wisely and get the results you pay for!!
