OK. This week I introduced both running and swimming--mini sessions of each to ease into things.

*1 mile run--was no problem but shins are quite tight now (my physical therapist recommended a stretch for this).

*500m swim--was doable once I warmed up a bit--by the halfway point I managed to breath (usu.) every 1.5 strokes and did not need to stand at end of the lane so long after each lap trying to catch my breath.

I can do this.
