Fat to Fit?

First , my confession :
I put on 20lbs between American Thanksgiving and Christmas!!!

So of course, I wasn't too happy and promptly went for a run and did sit-ups. I lost 5 lbs almost right away. Even my belly started to pull up a bit!

But that was the end of it. For one month, no weight loss, no muscle gain despite
1) changing my diet,
2) swimming 3 times a week and
3) doing some weights at the gym!!!

So... I hired a trainer.

My husband immediately offered alternatives, because after all, I've done this before and simply wasted hundreds of dollars. I could eat more protein, cut out the sugar, go to bed a tiny bit hungry... But I was tired of stabbing in the dark. I was willing to work hard, but I wanted to see results.

I did some research first(online mostly) and decided that the plan was to meet the trainer every week and get a workout plus nutritional guidelines every week.

Well, I found a trainer with experience and certification who worked out of my gym. It's been about a month since I started and I have lost about 5 more pounds, but more importantly : I actually fit in some of my old clothes again!!! CRAZY but true! I'm not starving either. In fact, I eat quite a bit!

Here's what I've been doing :
Swim :
1h 2x a week, and 1.5h on Sat morns
Weights :
2x a week : brutal, high rep, low weight.
It's all about form though. I have no injuries in spite of the workout!!

1. squats till my legs burn
2. more squats,
3. lunges with my legs on fire.
   
4. stagger to do chest press,
5. flop to the bench for lats,
6. glue myself to the mirror for shoulders,
7. stick myself to the wall for biceps ,
   
8. yank on a cord until my triceps lockup,
   
9. yank on the rope for more triceps
10. core, core, core for about 5min.-- I'm completely whipped and lifeless now

I am just adding cardio now, in tiny bits of 15-50 min cruises with nothing in zone 5. I won't venture there until next week, I think..
