Beginning With Kettlebells And Confused

Hi, I’m a female newbie. I have the Enter the Kettlebell book and DVD and an 18 pound kettlebell and a 26 pound kettlebell. I’m confused. Why are there only 2 exercises in the program minimum? That doesn’t sound like enough different angles. Has it worked well for any of you? I’m into sports so I need performance, not big bulky muscles. Could someone please explain why a mere 2 exercises would help me? That doesn’t seem like enough variety.

I’m also confused about eating. The Warrior Diet and other methods contradict each other. Which one actually works? What workout should I do to lose weight? Only around 5 pounds.

How often should I stretch? Once a day? Twice a day? Every other day?
