Have recently joined a gym, and have been trying out various classes to find the ones that suit me. I'm fairly unfit, and about 4 stone overweight.
Today I tried out the pool, and managed to swim 50 lengths (think it is a 25m pool) in 50 minutes. All the lengths were breaststroke. Is this enough? Is there anyway I can make it a bit 'harder' so that it is more worthwhile?
I'm trying to lose weight and tone up rather than build muscle. I'm not a strong swimmer, and don't have any proper 'technique'.
