Fitness calculators
I just found a website that has a whole bunch of fitness calculators for things like BMI, estimating how much water you need daily, how many calories based on you metabolic rate, your max heart rates for weight loss and cardio, etc. Sort fun to poke around.

That's the link to the calculators for women, obviously, but on that page, in the red bar near the top, is a pulldown menu for men that will give you guys the link for your calculators.
Have fun!
