There is no right or wrong.
If you enjoy it, then all the power to you. I think what irks people though is the fact they are claiming that "crossfit" is the best way to get strong and build endurance. Crossfit comes across as "holier than thou" and they are preying on peoples lack of knowledge to convert them to a system that, by design, offers nothing of benefit over conventional strength and endurance training. Sure it mixes things up and if that's what you need to keep yourself interested in working out congrats but don't let it fool you into thinking that it's the best, easiest, or blah blah way to get in shape because it's not.

In fact it's actually detrimental to building muscle and I would say your risk of injury is substantially higher doing those retard lifts and timing yourself. With fatigue comes poor form, with poor form comes injury.

Berz out.
