Matthieu -
If you want strictly o-lifting/strength, you can do Mike Burgener's WOD at
www.mikesgym.org. I program a lot like him, so our WODs look fairly similar in many senses, but I do add a little bit of conditioning here, whereas he does lifting exclusively. Either one will get you stronger without a doubt.
If you want to jump in here, I'd actually suggest going back in the archives to the beginning of this strength cycle (started Feb 9) and start there, then jump in with the current WOD when we start the big cycle again in about 5 weeks.
