i thought i'd have a right good workout tonight,did freestyle and breastroke alternately 50's but after 750metres of not too fast a swim my calf muscles started to twinge/cramp up,cos i've had this before i eased off and just did breastroke for another1500metres by this time it had gone,so i returnes to alternate freestyle then breastroke every 25 for the last 750 this with occasional rest was ok...i've always thought it was lack of salt but whats the deal with cramps cos it really bugs me ,but not all the time?
