Nutterbuster, thanks for starting the whole conversation about the doing the challenge it really motivated me to take my fitness to the next level.
After starting the KB mile challenge. I completely got my nutrition in check (measuring all foods, one cheat meal a week only, and no alcohol for the last 12 weeks) I have lost 24 pounds and feel great. My Marine unit is have a reunion in Oct and I turn 50 the same month, I plan on being under 10% body fat for both of those events. I am really excited to see how much easier it is to climb trees this upcoming season.
I also started adding in weighted walking lunges for time once a week, and I think I have gotten way more out of that then the KB mile. I am up to a 90 walking lunges in 4:30 with a 53lbs KB held goblet style. I dread doing it every week but it will really help with leg strength to drag a deer out this year. If anyone tries this please make sure you do not have any injuries and start with like 20lbs for 40 walking lunges and move up every week. Do not try 90 with a heavy weight first time.
