Overall health challenge. I am trying to cut out sugar from my diet as much as possible. No soda or fruit juice, no candy or desserts. I also want to try to get back to lifting some heavier weights. 2 years ago I had a herniated disc in my back and it took about 2 months to be able to get back to just baseline physical activity. When I did get back to lifting weights a couple times a week I did it a much lighter weight and even though I have consistently lifted at least twice a week I haven't really pushed myself weight wise for fear I would end up hurting myself again. But this year I did have a bit of a flare up of the disc issue but was able to manage my way through it without aggravating it further and ending up out of commission. So, I think I have a good sense now of how far I can push myself. Maybe I won't try to lift as heavy as I used to but increase the weight a bit from what I am doing now.
