We have a stationary bike and a treadmill that go literally unused. Then I have a wheel on fluid trainer (used $50 craigslist) and Zwift ($15 month) has me riding 120 miles and pulling 12,000 feet of incline per week, 600 miles/48,000 + feet just in the past 30 days.
A year ago I was a couch dweller. Yes I have made numerous adjustments to my bike and worked through pain and agony especally in my hands but other places also. I cannot wait for spring and hitting the roads.
