Does the personal trainer have a quality certification?  What about a degree?  Have they been certified to train in different styles?  Have they done extensive research into what they do?

Can they teach?!?!  Can they teach you?!?!?

How many clients have been instructed by the personal trainer?  1, 2, 50, 100, 500, thousands?  Think that makes a difference?  Sure it does!

Gosh, think about it…walking on a treadmill is boring!  Working out with a group is fun, exercise outside is exhilirating, weight lifting is more fun that cardio, laughing while working out keeps you coming back, a nice setting/location makes it more enjoyable…whatever it is that makes working out more enjoyable, that's what you want!  Go find your fun!

My favorite is going outside and getting on a bike.  Since I am in San Jose, I stay off the roads and go into the hills.  Maybe you like to skate?  Maybe you like to run?  It is all good as long as you do it, and do it regularly.
