The biggest tip I can give you is to work on technique. Once you can swim efficiently then you can start working on endurance and it will come SO much easier to you. You won't be fighting yourself in the water the whole time. Start small and you'll get there in no time!

I also started swimming again this week, i have been twice this week and thoroughly enjoyed both workouts

I have been twice as well! I love how I feel at the end of the workout..just tired enough that I can feel I did something but not completely wiped out like I did after using the treadmill..

Swimming is so much more enjoyable than going to the gym etc. I feel so nice after a hard day at work then doing a workout in the pool, I always sleep well after swimming too xxx
