I posted recently that I was starting to swim while the little girl I nanny for has her lesson. I started 3 weeks ago and afterwards I HURT! For several days after my shoulders, wrists and fingers were very sore. Nevertheless I decided to persevere. The following week her dad decided to take her so I didn't swim and then last week she had an eye infection so we didn't go. Needless to say I was worried when I got in the water yesterday!
I decided to adapt my swimming style and mainly use my legs rather than my arms. I probably looked utterly ridiculous next to the "proper" swimmers but I woke up this morning with no pain or stiffness soi think it paid off!
I've also noticed that since we took up running, I've had no pain in my ins or iOS which was quite a problem for me before then. Perhaps exercise is the key for me!
