I need to building upper body strength

I started going to a chair exercise program at our local mall.  This is led by the U of M School of Klnesiology Monday, Wednesday and Friday from 9-10 AM.  This is just what I was thinking that I would like to do  I have gone to two sessions so far.  We begin with a half hour of stretching and resistance band workouts in and out of the chair.  We then do 20 minutes of aerobic movement to elevate the heart rate.  The last ten minutes is a warm down back in the chair.

When I started working my arms I could feel the strain.  Others could continue, but I kept taking brief pauses to give myself a rest. That is when I realized that I need to build some strength.

I will be working on arm movements that lift, hold in position and raise above my head.  I will start out without added weight in my hands.  Just the weight of my arms is enough of a challenge. I used to lift 2 to 5 pound dumbbells , but I quit doing that and I see the result of stopping that practice.  I can do some of these exercises while I am on my stationary bike.  I like to keep the hands on the bike while I ride the street.

The need to build upper body strength makes sense for me.  You can see the various hand positions that I have on the drop handlebars.  The upper body strength that I have holds me up during a full day of riding.  This was a wake up call for me to build up some muscles that do not get much use while I ride.
