Achy muscles

I am a little tired of the weather this last week, way to hot for April. Two days at 98, then 96, 87, today around 76~ which is more the normal this time of year.
I added weights to my work out this week and I am feeling it a little. I probably will leave the weights where they are. At my age just how much weights do I need to be able to handle? I have found that I like the cross trainer much, much more then the treadmill.

All my rose bushes have finally bloomed. My garden is just full of color. I will post some pictures later after work.

After all the fires in Calif. last summer (every summer) I am saddened to hear about the fires in S.C. Fires are just bad no matter where they are!
