What is your goal here? If it's just general health and fitness and looking good, then I think you should just alternate strength and biking each day/workout session. This is what I do (using the strength and HIIT classes on the Peloton app in addition to the rides - 30 mins per workout) and I'm really happy with the way I look and feel. I'm 35 with two kids and on a recent vacation my long-time friends said, impromptu, that I looked better than ever. However, I am not the level of fit to win any kind of lifting contests or do a long-distance ride/run. If you have particular fitness goals, you should think about what they are and shift your workout plan accordingly more towards strength or riding.
