So we went off swimming today. I was really struggling to do the breaststroke, dunno why, I was doing it all properly, push off the wall, kick loads and move arms, just didn't succeed today. So I did 2 lengths of not really stroking, 2 lengths on my back and many hamstring exercises. GGtGG said "Come on then, get out" but I tried again to do a breath breaststroke, still couldn't, dunno what the issue was
