Can I do Zone 2 training on a recumbent bike, and if so, are there any specific considerations I need to take into account to ensure Im getting the most out of my workout? Ive heard that recumbent bikes can be great for recovery rides and easy spins, but Im not sure if theyre suitable for more structured training. Do I need to adjust my power output or cadence to compensate for the different riding position, and are there any particular drills or exercises that are better suited to recumbent bikes? Additionally, how do I know if Im actually in Zone 2 on a recumbent bike - can I rely on heart rate and perceived exertion, or do I need to use a different metric?
