I admit my gym use dropped off in the second half of the year. I was getting busier at work and the time I spent in sports therapy took up my gym time. But I did start going back right after the marathon, though mostly for the hot tub.
Today I just couldn't face the cold outside and decided to put in some time on the stationary bike and get serious again about my core exercises. I was doing pretty well in the first half of the year and kinda let that go.
I was ashamed how wiped out I felt after 25 minutes on the bike and how far I've fallen in terms of pushups, situps, pullups, free weights, etc. Well, it's going to be a long winter.
