HOW DO I BURN MAXIMUM KILOJOULES IN THE POOL?
Swimming is amazing for fitness. The water resistance means you work five times harder than running outdoors. For best results, stick to freestyle (you can use other strokes as a warm-up). Use the pool clock to gauge your times swimming 200m, 100m, 50m and 25m, then do some pace work. If your 200m time is three minutes, aim for 2 x 200m in 4:00, 2 x in 3:50, 2 x in 3:40, 2 x in 3:30, 2 x in 3:20. Slowly increase speed and decrease rest time as you improve.
