32. Rocks for dinner???

Seriously, have I been eating rocks for dinner? The past two days I've felt like my body is filled with lead or rocks or concrete or something. I just can't get going. The most jumps that I've been able to do without tripping lately is 10. 1300 jumps take forever when you trip every 10 or fewer jumps. And the exercises are killing me way sooner than they normally do. It is a major struggle to finish out the sets. I just keep plugging away, but man it would be nice to get some strength back. Blarg.
