@becsbuddy I am very discouraged. We had been walking every other day and I would do my bike on alternate days but I am discovering that on the day following walking my thighs and knees are killing me. It must be from the impact of walking on a hard surface even though the track is not as hard as pavement, and I walked a lot on a treadmill when I was going to my health club.

Yesterday I could do very little early in the day but as the day progressed things got slightly better so I did a video workout and my bike in the evening. A friend suggested that some medications can contribute to aching muscles and sure enough, my cholesterol medication is one that can so I have a note to my doctor on the portal to see if that could be the problem and find out if a different medication could be used instead. I will probably try walking on the track again today but I will wear different sneakers, maybe that will help.
