I started working with a trainer for the first time in my life in January. It's made such a huge difference that I wish I'd done it sooner. She really helps me with my form, encourages me, and gets me to do things I'd never have thought of such as doing bicep curls while standing on one leg on an upside down Bosu ball. She keeps it fun and interesting while pushing me just enough (but not too much) and she's become a real friend. I agree that it's a great investment in your health and well-being and I highly recommend it if it's at all within budget.
