Looks like you're doing pretty well. I have been running a boot camp for over 3 years. I started off slow too, and then built up. it is hard for my area to get people to exercise, I believe we are on the top 5 in the nation for overweight and obesity. But I am doing well. Now I am transitionaning to CF and since i am the only one in all of this region (South East Texas) to be offering it and people get intimidated by it, so looks Like i have to start from scratch.
However, I do have a lot of my clients that are liking it, and have said they will stick with me on the transition.
I have about 15, and some others I have found on the forum or that I meet and they are interested and I have given them some free classes.
Now ideas for for the beach, I have done for the last 3 years, a beach challenge once a year. I have the beach about 1 and half hour away from me. my website is down so I could tell you to check out my videos and pics but they are not available anymore.
But what I have was: I have tires, 18 wheelers, and big tractor tires, lots of sand bags, some 3 foot logs that are about 33 lbs each, 5 gallon water cans, some military euqipment i kept from the military, such as back packs, i have 2 50 goot ropes, and a lot fo tother stuff I have acquired or found on the way.
What I have done is built like obsstacle courses, I get there the day before, and all night till about 4 am or so, me and one or two of my friends, set up obstacles, just what ever it is. Such as the y have to carry a water can from one sand dune to the other, or I give them a poncho they have to carry on their military backpack, and they have to make a litter carry, like a bed sort of.
I make two teams, no matter how many people show up. Usually get about 20 to 27 or so. The first I do is give them all a Physical fitness test, that I used in the military as well. it is 2 minute push ups, 2 minute sit ups, and 2 mile run. At the end of the two miles, thats where they start their race back to the start line. This is what I did this year. it was awesome, they had fun.
I think just been creative, jsut find anything you can use and do obstacles and stuff. Now with CF i am already thinking of doing some kind of challenge at the beach with some of the otehr affiliates that are abotu to 5 hours away, I have talked to them and I am gonna go meet them this week.
