I managed a good swim at lunchtime today and feel that I maintained fairly neat form. After work I had my monthly back and shoulder massage - mostly that's to keep work-induced stiffness in check, but today there was lower back ache from back extension exercises at the gym. Now I've just done a basic set of rollering and stretches. Even though yesterday was quite tough on my knees they've felt OK today, just a little issue with the right patellar tendon. So not right, but going in the right direction.
