For Crossfit references/resources: the daddy of them all is of course - http://www.crossfit.com/
You can find a description and details of the exercises as follows with proper form, etc:http://www.crossfit.com/cf-info/excercise.html
Note that on the home page @ crossfit.com, they actually show the workout of the days (wod). e.g. for MONDAY 120716 -
21-15-9 reps of:
Clean 135 pounds
ie the workout is called Elizabeth, and you do 3 sets of 21 reps, 15 reps and 9 reps (no scheduled rest in between), alternating between cleans and ring dips and you are supposed to try to finish the workout as quickly as possible (record your time). Obviously if you are starting out you scale - so that you do as close to 135 lbs as possible.
Yes, it is not cheap - and will run about $200 a month - but the way I rationalize this is that it's in between the cost of a personal trainer and just a standard gym membership. It's in small(er) groups who go through the WOD altogether so there's a certain amount of group suffering / camaraderie / competition to push yourself...
And this works for me (and a lot of people I think). If you can be (almost) entirely self motivated, you can actually just try following their workouts of the day found on the home page of www.crossfit.com. Many crossfit gyms will have their own WODs - so you can find one in city xyz and they will often have it on their own website or after you like them on facebook they will post them there. I also notice that my regular gym is also starting to do small crossfit / trx classes. I'm not sure how much they charge but I imagine it's less given you're already paying the membership fee.
Personally I've gotten a lot out of it... and I just signed up to do another crossfit bootcamp that starts tomorrow. The bootcamp I'm doing runs 5 days a week for 4 weeks with 45 minutes each session. It costs about $220 incl tax and I just finished one this past Friday.
