The 30 minute boot camp at Elite FX is awesome.  First off, its indoors.  There are so many boot camps that are outdoors- sorry, I just can't do it most months of the year!  Secondly, its pretty intense, fast paced circuit training.  I am in pretty decent condition and I still find this class challenging.  We do 5 minutes in stations which include kettle bells, burpees/squats, running stairs, spinning, and boxing.  Its the perfect blend of cardio and strength training, and I always feel challenged.  Lee doesn't let you slack off, and provides slightly different exercises for more advanced people.  -Kellie J.
