Okay - well, how about you start with this:
Make a commitment to show up at the gym three days a week. You don't actually have to train - you have to show up on the floor ready to train.
Here's your entire 3-days a week workout for the next month:
3x5-8 for each of the following, not counting warmup sets.
Deadlifts - free Olympic barbell, any style (my fave is RDL, off the floor is great too)
Squats - free Olympic barbell squats, below parellel
T-bar or bent over barbell rows - one arm dumbbell rows is another option here if you prefer or want a little variety
Bench press: Flat or low incline barbell press.
Chins or self-assisted chins. If you're doing self-assisted, do 'em by standing on a bench so you're at eye-level. Use a shoulder-width or narrower grip and lower to a count of five. Get back to "up" any way you can. WAY BETTER than lat pulldowns. You'll see why when your lats and your abs hurt when you breathe the next day.
Military press or push press. Standing. Dumbbell or barbell. No machines.
Weighted crunches on a swiss or bosu ball. Yep, 5-8 reps, just like the other stuff
20-minutes of post-workout cycling OR incline walking on a treadmill. Don't hold the handles while you walk. No elliptical.
Spend a couple of minutes with some slow static stretches after you train (not before - you can do dynamic stuff before but static stretches come after)
On the off-days, go for a 20-30 minute walk, preferably after dinner. It'll help you metabolize carbohydrate better by activating glucose transporters.
For your diet, the easiest suggestion I can offer you is this: pretend you have celiac for a little while and stop eating wheat. This makes it slightly more inconvenient to eat crap like muffins, bagels and pasta - and besides, wheat makes a LOT of people particularly hungry (I'm one of 'em).
Lean heavily on protein-dense foods, make sure you eat plenty of healthy fat, limit your starches to the meal before and the meal after you train. Every other meal is protein, produce and healthy fat.
While you do this, track your intake on
FitDay - Free Weight Loss and Diet Journal and post up the average in a few days so we can help you fine-tune it.
How does this sound?
