...and don't say "the gym".
A bit of background: I'm 5'9" or so. 36" waist for jeans. 2 years ago I was wearing 33" combats and walking a good 4 miles or so a day, mainly on hills, now the only exercise I get is the walk to my car. My job involves around 10 hours a day of sitting down. The big problem is with me, whenever I gain weight it's only on my belly, nowhere else.
I'm aiming to get back to the shape I used to be in (my cardio's crap these days) and hopefully gain some muscle mass/definition since about the heaviest thing I lift is my pedalboard.
The "local" gym is miles off and not particularly good, so I'm looking to keep to outdoors stuff and stuff I can do at home, which I'm having trouble finding. I've got a set of dumbbells and I'll be going over some of the exercises in the old Baseball for Dummies book I got a while back, and once the weather clears up I'll start doing some cycling again, but other than that I haven't got a clue where to start.
Diet isn't a problem, it's almost entirely natural products, plenty of protein. The only possible issue is I get through a massive amount of chocolate (72% stuff) a week, but I'm going to cut that down.
Given the above, is there anything I should be focusing on?
TLDR: exercises/advice for a total noob, that don't involve gyms. Go.
