I'm 78. Have a basic home gym that's not as elaborate as Gobicycling's setup. I'm jealous. Basic adjustable weight bench and a set of dumbbells. I alternate sets for chest/shoulders and arms/back. When the Wyoming weather allows, I alternate strength training says with rides. This month, when the high for tomorrow is forecast to 10 below, I alternate weights session with yoga/stretching and pray for better weather.
