Exercise a Priority?

I'll be honest I don't make exercise a priority. I try to move as much as I can during the day. I lift heavy things all day at work so I'm using my muscles. But to actually have a "work out", I don't. I know I should for many reasons, but it just gets put to the end of my 'to do' list. It's also sad to say that I worry about putting that much work into my body to only be disappointed when I see all the excess skin that I will never be able to have removed. I know I shouldn't look at it that way but...

to lose weight- 90 %is diet- 10% is exercise. But exercise helps to retain our muscles and improves circulation, and improves lymphatic circulation, and helps with heart, brain and other organs. 

but- if you do some - physical work at the job - that may be OK. 

I bought one of the fitbit.  I like it because it tell me how well I sleep, and how much  or little I move... 

post op PSI had as little as 2000 steps recorded... that lasted for 2 weeks.. then I was in a car accident - again- I had not moved much... so my daily average for the next 2 weeks was like 3,000 steps.. in 4 weeks I lost a lot of muscles mass... I am over 50 - so it will take me months to rebuild those muscles... but I know I have to do it...

strong muscles emans strong bones... good circulation... 

The older I get I read more and more about how lifting weights, using muscles becomes more important than cardio type exercise. I can tell my muscles are not what they use to be and I need them for the type of work I do! I come home from work sore much more often now than I use too. I would love to build my strength back up to where it was before and even better, but I am not sure I have it in me to be THAT dedicated.
