Approaching 80yo here. I just moved an old TV out of the basement - but, given my back, I paid someone to move it. It weighed a ton. Also got a "Smart TV" upstairs after 15 years with a huge console Hitachi and had it hauled away along with another desktop TV. Amazing how this stuff piles up over the years!!

I use a mag trainer with a wood block support on the front tire to keep things level on an old mtn bike with cadence and HRM and play Spinerval videos on a separate monitor from the TV. I would 2nd the suggestion of keeping the Nordic Track as variety and to train different muscles. Are you doing resistance training?
