Nu? Someone with your level of sechel can turn this around in a matter of months. You know its important, you know how to do it, and the timing could’nt be better (the warm weather is only 10-12 weeks away)
From what I gather of your other posts, you’re in your mid-30s, and have a pretty controlable, predictable scedule. Getting in shape should be a piece of cake (pun intended).
Set your mind to it, and you’ll be in tip-top shape in no time.
