Haven't really been participating but am in a fitness challenge with 3 other friends. Intense 30 minute workouts, 3 x's a week plus my regular biking and hiking.
at end of week 3 I am down 4.2 pounds but more important - I have dropped 4% of body fat!!! 3 more weeks to go, hoping for at least 8 pounds and to lose 6% of body fat
