Interruptions to my exercise program

I was able to exercise only one evening this past week. My dad had to be rushed to the ER for attention due to a bad reaction to a wasp sting. That killed Monday exercise. Tuesday is my regular night for my writing group. I exercised Wednesday but could not Thursday because of Haden's Senior Awards program. Friday is always out because they close at 5:00... too late for me to go after work.

Next week I will have only Wednesday and Thursday available because A New U is closed on Monday for the holiday.

I am still doing only two rounds of the three rounds of machine exercise. The trainer recommends working up to the three rounds. I am pretty tired after the two rounds and I dread getting up to three rounds but I must. I am not getting my heart rate up to the 85% range where I am supposed to be. I'm only in about the 75% range. At this point, I don't seem to go any faster which, I assume would get my heart rate up. Hopefully that will come in time. I am happy enough that I'm exercising. Even short of the trainer's expectations, I'm much better off doing this.
