@csimadera1 There’s no question (and it’s very well-documented) that staying active, walking a few miles on a regular basis, bicycling, etc. is great for overall health.

But, as you can tell from the tone of the discussions on those links above, this involves more than that. In this case we’re talking about being injected with a very toxic substance (ADT), that’s going to affect you on the cellular level, and wreak havoc on your metabolism (as it pushes your testosterone levels to near-zero).

The loss of energy that you’ll experience from near-zero testosterone levels will show up in basic home activities including walking, bicycling - even simple activities like yard work and gardening. Remember that the hormone that gives you all of your male characteristics, including strength, fitness, endurance, etc, is basically being suppressed. Your testosterone levels will be below most women’s levels. You’ll be going through what’s often referred to as “male menopause.”

That’s where resistance-training exercise comes in. Somehow - and I don’t know the science behind this - maintaining lean muscle mass minimizes the adverse side-effects of ADT. (Other references I’ve read mention that high intensity interval training (HIIT) will work as well.)

If you’re able to, start resistance-training (or HIIT) exercise well before that first ADT injection. Once the side-effects of ADT start, it’s difficult then to have the strength & endurance to start.

Activity in the bedroom can be affected as well. Testosterone being suppressed usually affects libido; low libido may affect performance. (My libido went to zero.) However….. despite my having no libido while on Eligard, everything still worked. From what I was told by my medical oncologist, the key is to continue “doing it,” despite the “want to” not being there.

Though I have no data to support this (only my MO’s advice that it would work - and it did), my experience not having ED while on ADT might be related to me ramping up my resistance-training exercises and cardio programs to minimize the side-effects of hormone therapy; that might(?) also have the side-benefit of keeping the blood flowing “down there” as well (since ED is often much about blood flow and hydraulics, even for those not on ADT).

Libido eventually returned to normal when testosterone returned to normal.
