Whenever you feel well enough, exercise. This was a huge help for me before my mastectomy. I finished chemo in January and started to feel human in February. In March, I started exercising and eating well again. It may not seem worth it to exercise for such a short time (I had about 6 weeks between feeling good and my surgery), but it has made a huge difference.
Squats are fantastic because that’s how you’re going to want to sit down/lower yourself onto a chair or the toilet.
Overall leg strength is also so important because you can’t use your arms except for some no pressure balancing. You’re going to want your abs to be strong, even though they’re going to feel sore. They’re probably not actually sore though, it’s just the belly skin pulled tightly. You’ll need your abs to shimmy into position when you can’t use your arms, and you’ll need them to sit up, lay back, and gain balance.
Of course you can do these things with assistance, but you are eventually going to have to do it alone, and that’s a good thing, as long as you’re not pushing yourself with too much, too fast. But if you’re anything like me, you’re going to want your independence back ASAP.
Listen to your body, but don’t be afraid. I was terrified to sit up because I thought my gut was going to come out. It’s irrational, but the thought was there. That’s the kind of afraid you don’t need to be. Your gut isn’t going to fall out. Not even when you cough.
Don’t over do it, but don’t be afraid to try.
And of course, the sequence of your treatment or your physical condition may not allow for exercise. You may feel like garbage all the time, or you may have your surgery immediately, with no time to prepare. You may not be able to or even want to do it the way I was able to, but if you can even just squeeze in some walks or squats or lunges, you’ll thank yourself later, trust me!
