Personal Trainer - Swimming
Swimming is a fantastic way to gain the stamina, strength and body-toning that you want, swimming puts no pressure on joints while you burn those calories.
It work's every muscle group in the body and when mixed with other training session's give's you great lung control and fanastic all-round fitness.
I have learnt from experience the importance of swimming training for all of the other activities i compete and train in, it's the most important part of the Triathlon if you intend to try this sport...
