SINKO (!) de Mayo

I went to a "deep water arobics class" tonight--a first for me....a bunch of women in the deep end of a pool (over 7 feet) with these floaty things around our waists. The idea seemd to be to follow the moves of the instructor (ie. "knees up" "legs out" "alternate kicks to the side")--all while you stayed suspended with your legs going down. I, however, kept tipping forward--face in water, limbs flailing. The instructor then changed my belt thing around so the heavy part was in the front. I still could not maintain the "body perpendicular to the water" stance..but this time I ended up floating on my back. So, we then put weights around my ankles. This , at last, kept my head above water..while I watched in amazement what the others were doing!
