I have 0 Energy and 0 Motivation....

Try listening to audiobooks while you walk the dog. If it's an action-packed story line, you'll be anxious to get back into it each day. If you ONLY let yourself listen to it on walks, you might be even more motivated to set out each day. Start with 5 minutes per day, just to prove to yourself that you CAN do it and to build the habit into your day. You'll feel better about yourself, your mental toughness will build, and you will gain momentum. If you can do it early in the day, even better. Then you get to go around the rest of the day with a teeny bit of self-righteousness, knowing that you already kicked some butt.

Slow and easy wins the race- be kind and gentle with yourself- it is your body and you CAN do this!!! don't give up!

I can understand that your serious health issues that are now behind you would drain you from routine things like diet and exercise - seem trite in comparison. But you ARE here, so I wouldn't say ZERO motivation! Probably not zero energy, either.

I have taken Pilates for about 4 1/2 years and it's helped tremendously with my lower back issues - I almost never have pain there any more. It's helped with other issues, too, such as a bad knee and weak ankles and other things like that. It takes so much focus that it's great as a stress reducer, too, because you can't really be thinking about anything other than what your body is doing, since every muscle has to participate in every move in one way or another (a lot of opposition is built into Pilates). I hope you enjoy it and will soon be hooked. Are you thinking about starting on the machine or on the mat? I would recommend the machine as easier and safer to start with and you get a great isometric workout while you're strengthening your various muscles.

Something that might help is to have really low goals so that the "achievability" aspect makes it seem silly-easy.

After beating back my cancer, my first victories were very small. Walking to the corner store (only maybe 200 meters) was a victory. Walking once around the block, no matter how many pauses, was a victory. Walking around the block without stopping was a victory.

If your surgery + chemo experience was anything like mine was, your body has been through the wringer a couple times over. Smaller goals can seem more achievable, meaning that taking that first step seems more doable. As your capacity and confidence builds, you'll find the motivation coming back.

When I am feeling low, I blast some music that motivates me. Crank up a "Turn Down For What", and it is hard to stand still. Get someone else involved, a friend, a relative, a coworker. Hopefully you have off days that don't collide and you can motivate each other even if you are not in the same area. Good Luck!
