Adding to that, you are best to separate the Strength Training (weights) from Endurance Training (bike) by as much time as is practical.
- Ex: Do Strength Training in the morning, and do Endurance Training in the evening, both on the same day.
That is done because the physiological goals of each effort are typically counter to each other and you will get the best return from each when they are separated, not done on the heels of the other.
