Fun & Fitness over 50

Today (Wed.) I am still not sore from doing an upper body workout on Monday (my "rest" day) in spite of having worked out just as hard or harder than usual. I guess that means it's time to change my routine!
Not sure what I will do yet. I could hire the trainer at the gym to come up with a new routine or I could just "browse" the machines and select ones I haven't been using. This would require me to figure out how to do the exercise from the instructions on the machine.
I would like to find a trainer that is also a biker or has experience working with bikers but just a good one will do, I suppose.
Also, I would like to have a male trainer. The only one available through my local Planet Fitness is female. Maybe I could check some of the other locations. All I need is one training session once in awhile.
That brings up another thing. It would be nice to have a physician that is either a sports medicine specialist or bikes himself.
Perhaps you can see I'm thinking out loud here. But it has helped. I think the idea about checking with the other PF locations is doable.
