Recommendations for arm band to hold iphone during gym or exercise I am looking for people's recommendations and warnings for arms bands to hold an already encased iphone 3G. I am planning to do HIIT and weights and want to use the iphone for my interval timings instead of paying for the gymboss timer. What I am looking for:

* no need to remove existing case;

* can handle a lot of vibrations and movement;

* sturdy;

* headphones do not get tangled

Any input from anyone dealing with this is or something similar is welcome.

Tour-de-France vs. quickie workouts: Which is better?

1 hour workout vs. 3 hour workout... which is more effective for weight loss and weight loss only? A friend and I are unable to agree. We all know the key to weight loss is, more calories burned than consumed, correct? A friend of mine, who has lost 100 lbs. in a year, asserts that you NEVER should do more than an hour of cardio and that HIIT workouts (20 minutes or so) three times a week are even more effective than a regular hour, say, on the elliptical. He also asserts that working out any more than that will do nothing for you.

I say, well, if you eat 1600 calories in a day, and work out for three hours, burning 1000 calories or more (say, rowing machines, walking, alternating jogging and walking, stationary bike, etc.), you will have a 1000 calorie deficit and your body will only have 600 calories to run on, assuming you are vigilant and not making assumptions about the total calories burned. I also am asserting that professional athletes can work out up to 6 hours a day, 7 days a week, so if you are in shape, the time dedicated should not be an issue.

Assuming you eat every four hours except while sleeping, and are performing mostly cardio with weights and toning exercises (lunges, squats, pushups, free weights) thrown in every other day, and your only goal is to lose weight... why wouldn't taking the time to burn more calories be BETTER for weight loss? Is there some magical point at which this stops working?

My doctor AND a nutritionist have both told me that cutting below 1200 calories per day will put my body into shock. Exercise, from what I can see, is the only way to raise my calorie deficit. However, there has been much debate on MeFi whether or not exercise can truly impact weight loss. Please help me understand this better.

Personal aside: When I wanted to maintain my weight, I worked out an hour every day and was perfectly happy with that. My weight never went any lower. I have been working out regularly for at least eight years and am in reasonably good shape; I am not proposing to work out to the point of injury, only to the point of a significant calorie deficit.

Make me vomit!

I want you to help make me vomit! So, summer is upon us and that means two things: grilling and rugby sevens. I play rugby through out the year, but sevens is a bit of a different beast and as such I need to move a lot faster than I do now. I already do the lifting and cardio parts on my own, but I am looking to throw in high intensity interval training (HIIT) to develop greater speed and endurance.

I need help figuring out some good programs though, as most information I have found online can be summarized as "Run fast for a little bit, then jog for a little bit, repeat." I have some criteria though:

*I want to do this on my feet, no bikes or rowers or other such machines.
*It shouldn't use any equipment.
*It can be performed on a stretch of road or a field. I don't have track access.
*It has to be intense. At the end of most lifting or cardio workouts, I want to vomit. I want this to be the same, if not even more intense.

So, there you go. Be creative, I'm looking forward to some interesting workouts!
