We are well into the second week of our fitness program now! Worked out on all three days, kept it to a 30 to 45 minute workout each time. When I have reached muscle exhaustion, or am starting to feel a little sick, I either ramp down the intensity, or shorten the workout. I was happy to find that the low-impact workout today didn’t really seem very hard, and that I was able to finish all three rounds. We are both finding the stretching at the end of the workouts to be very nice, and I think I am noticing some gains in strength and endurance!
