Joseph Pilates coined the phrase "Look better in 10 Sessions, feel better in 20 Sessions, have a completely new body in 30 Sessions."
I know people who join the gym and give it a good shot. After a year, they see marginal results. They took a week off before their vacation, then took a week off the week after their vacation so they could "catch up" on their work. Excuses, excuses.
If you hire a personal trainer, a good one, this person will motivate you. This person will encourage you reach your goals. This person will push you beyond what you think you are capable of.
Do you REALLY want results? Well, if you are committed and REALLY want results, it can happen with the right personal trainer. I know you probably don't live in my neck of the woods, but if you gave me 30 sessions of your time, you would look better than you look today - for sure. It depends on how bad you want it. Commit to a qualified personal trainer and get started today. Don't wait for tomorrow that will never come for you.
Not all Pilates is equal. EDIT
