There is a paper just referenced on Emperical Cycling’s weekend instagram. The biochemical signaling from intense endurance exercise subsides after 3 hrs. The signaling after strength exercise lasts 18 hrs. At 66 I do an hr early in the morning, the weights at 1 pm. Take the next day completely off. If you ride after lifting too soon you block the biochemical signaling and dont benefit in terms of strength or hypertrophy
