Training Tip: Write down your weekly training results. Add more clothing layers over time. Compare notes. You should see improvements.

Then followed the float test, which is treading water (or just floating) in the deep end of the pool for 10 minutes without hanging on to the side. At the 9th minute, the lifeguard threw in life jackets to put on and swim to the poolside.

I passed easily without getting too tired, but still, ten minutes pass surprisingly slowly when you're treading water and watching the clock. Oh, I almost forgot, we had to do it with all our clothes on, which was great fun. Since then I do most of my swimming training in clothes which keeps me fit.

On most summers, half way through the week everyone came down wearing regular clothes every day. We advised them to dress in different clothes so they learn how that affected their activities.

We showed them how the weight of the clothes would help build up their strength, and how to do the survival clothes inflation. Aside from all that, not only the instructors but the students as well noticed how much easier it was to swim in their swimsuits, but that it is more fun to swim in their clothes.

Training Tip: Practice as a team and try different outfits to gain more experience. Go outdoors to lakes or the sea, swim longer distances and play around a lot so everyone has fun.
