WarmUp (WU) – 2 laps easy
6 x 100m / 1-2′ rest – 90%
Cool Down (CD) – as long as you want 🙂
Freestyle one lap, breaststroke one lap. Freestyle was done about 1breath every 5 strokes and 1 breath every 3 strokes for breaststroke.
Swim like a shark is chasing you!
Heart rate was in the high 90s even till the late evening. Great anaerobic workout!
