I found a Groupon for Gold's Gym.
$19 for a month, including two personal training sessions. I'm not really interested in the PT sessions, except maybe if I can get one to take all of my measurements as a BEFORE baseline.
I'm not unhappy with the shape I'm in, but I know that my muscles were bigger and more defined back when I was lifting weights, so I'm curious to see how much effort it takes to regain some of that.
I have a tendency to see a goal and then go for that goal with 150% effort. And with something like this, it would be very easy to hurt myself doing that, so I have to keep myself honest, realistic and patient.
I'm off to Gold's Gym now, to sign up and get started.
