Thanks. I've gotten good at modifying. I'm watching all of the workouts in advance so nothing comes as a surprise. I'm going to be careful while not being afraid to work hard. This morning, as part of a citizen's fire academy, I suited up in full bunker gear and went through a training smoke house carrying hose. In the Texas heat! That was probably more intense than anything I'll be doing in the next 90 days. Taking the rest of the day off (maybe some yoga), and looking forward to getting started tomorrow. I am going to try to take the yoga philosophy of taking what my body will give me each day, and showing my 47 year old self some compassion! But I'm not going to be afraid, either! Thanks for your encouragement!
