When it came to getting in shape, you only had a few choices.
You could slog it out in the gym by yourself and hope that your form and exercise choices and program were good enough to get you where you wanted to go (and hopefully get you there in one piece!)
You could hire a personal trainer and hope that her expertise and the accountability would yield results before it became too cost prohibitive to continue shelling out hundreds of dollars per week.
You could attend large, group fitness classes that were filled with enthusiasm but no real structure or individual attention or progression. It was fun while it was happening but you never felt like you were getting anywhere. And exercising in other people’s sweat tends to run its course really quickly.
