Boot Camp

So I tried the walking and did well. First day I did 4 1/2 miles, second day I did 5 1/2 miles.
Felt good.
Then I found this thing called Hoboken Boot Camp. I signed up for the two week free trial and I've been going 4 days a week (it's only offer 4 days) Monday through Thursday at 6:00am each morning. I've been getting up at 4:30am to get to this class.
I LOVE it. I know. I'm as shocked as the next guy. I who haven't moved at all in the past 5 years jumped in both feet and I'm doing strength training with weights and lots of cardio work.
Today he offered a class on Saturday and I went.
I was the only one there so I got a private lesson. Both good and bad. He kicked my ass up and down Sinatra drive. Working with the band doing squats and lifts and then doing mountain climbers and then side stair stepping on a bench and THEN bicycle legs into dips with my arms on the bench. 20 of each.
I think we did 7 sets but I don't know. By the last set I was dying. I didn't think I could do it. My legs were burning and my arms...well let's just say they did NOT want to support my body with the lifts.
But I DID it. All of it.
I'll go back Monday and because I'm a total masochist I'm actually looking forward to it!!!
