I completed a full hour's aquacise this morning, in the shallow end of the 25m pool.
Fifteen minutes in, and my thigh and calf muscles were screaming STOP, I decided to keep going to the half-hour mark, by which time they seem to have remembered what they were for.
My left knee reminded me I had a cartilage injury and told me to "stop doing those twisty sideways movements now. "
Apart from that, I had a really good workout, followed by a couple of lengths swimming (breastroke arms/front crawl legs.)
My first goal is to regain a good level of fitness. Only then will I start to look at shedding the 5kgs of extra weight I've gained over the past six months.
