The best exercise I'd recommend to anyone starting: the kettle bell. Do 50 reps (you'll need to break them up at the beginning) with 40-50lbs. If you don't see a change with those you never will.
I'm 8 weeks in to the 12 week programme. It's just 45 minutes three times a week and I'm stronger and healthier than I've ever been.
I don't know about the discipline so much - it's so addictive I can't wait to get in the gym! But it's definitely helped me cope with a very trying two months personally and professionally.
As for me: - stronglift 5x5, slightly moded: lift twice instead of thrice a week.
- a running program that i made up (run ~4 times a week, 200m x 8, 400m x 4, 5k trial, 1mi hill climb + 2mi run)
- bikram yoga once a week or every two weeks
- some crossfit workouts that i can do
I try to workout most days, resting completely only once or twice a week.
I hated lifting weights and running for my whole life, so it's quite enjoyable to spend four or five hours a week getting a great workout where my mind is constantly being challenged also.
The founder of the art called it "the triumph of intellect over brawn". But you will get fit practicing it...
1) get a good night's sleep [I actually lost about 20 lbs just by getting more than 1.5 hours a night of sleep]
2) eat a large breakfast [the best pattern is large breakfast, large lunch, light dinner]
3) take breaks whenever there's a respite in the work [just stand up and walk around a little bit before getting back to keyboard]
I've discarded even walking 3 miles due to breaking a sweat (I wear a suit to work).
Don't get me wrong, cycling is great exercise, I used to do 10 miles each way to English classes and I was healthier than I am now, but I can't see myself cycling to work.
My coworkers that I trust confirm that I just don't smell so its not a problem. I trust some of them to tell me if it is a problem and I will adjust accordingly.
Most of the time I don't see clients (I'm a software guy) and I'm wearing shorts and t-shirts (it is California).
When I did work in a slacks, dress shirt only position (for a very short time), I threw my beater bike in the trunk of my car and went out for rides at 5 (watched the clock).
Personally the less product I use, the less smelly and more natural feeling my skin and hair are. YMMV.
And I found that carrying a very lightweight backpack is my preferred way of carrying other clothes. I don't carry a laptop, just clothes for how cold it is in the morning and clean socks and such for the office. I leave a lot of clothes at work so I don't have to carry too much stuff.
Changing clothing and toweling (plus wearing shorts and t-shirts) should do the trick then, but I can't do that right now :) .
Also, California weather helps, I guess that wearing some heavier clothes you'd sweat a lot more, and thus possibly smell.
Also, I don't slog 12-15 hours per day with all night coding.
I avoid coffee and drink Lipton herbal tea.
easy to remember, easy to do, quick burst of energy; but don't get sweaty
Also - do wall pushups (25 at a shot) for 300 a day. As well as squat: hold for 1 min, every hour. Can do in bathroom or stairwell for privacy.
