What to do a lunch for Maxium weight lose

My story:

I am following the Intermediat IM plan that BT offers.  During the week, I am able to do one of the workouts during lunch in most cases.  I tried to get up early, but just can't do it.  So I either lift or run or swim.  (I have also been known to stretch my lunch to about 90 minutes instead of an hour on occasion )

That may change during the second half of the plan as the workouts may get longer.

If it were the off season, I would swim and lift during my lunch hours, and then run/ride after work for 60-90 minutes.  However, to maximize weight loss, lifting and RUNNING would probably burn most calories during that limited amount of time.

There is kind of a loaded question.  Fitness, health, injury, goals, etc, all play a factor.  But if you want to limit the scope to JUST about weight loss, then probably, yes.

I'm just saying that running probably gives you more bang for the buck, time wise.  It uses more muscles than other types of cardio.  Lifting may not burn as many while doing the activity, but increased muscle mass will cause you to burn more calories throughout the day.  But since you say you get injured with excessive running, then biking or swimming could be better.  I might lean towards swimming, since I like it more and I like how it tones the upper body.

If it were me, and time was a limiter, and I was 100% healthy, I would alternate with 30 min lifting one day, then 30 minutes running then next and maybe one swim a week.  But that's just me.

Also, all that will not amount to much if the diet isn't right.

I used to bring my bike to work and I could ride 50' in an hour during lunch. I always felt way better after my rides. I would quick change and then wash my hair and wipe down and I was back to work.

Do you have a place to ride outside during lunch hour? 

Key is stay healthy to be ready for IM training and I agree now is the time to lose weight. Me I want to drop 15-20 before my next IM. My plan is to ride lots...easiest for me, non weight bearing, I like it, and it tends not to make me hungry. How about that try and ride every day? 700 miles a month? Great for building up bike fitness which will help you next year...remember my saying..each pedal stroke will get you closer to your goal of being an IM.
