Crossfit Training

My personal trainer, frustrated that he hasn't been able to kill me yet, has started me on a new program. Crossfit training:

Here's the formula for a typical CrossFit workout: a warm-up, followed by three
to five sets of three to five repetitions of a multi-joint exercise like squats,
pull-ups, push-ups, dead lifts or bench presses. Next, a 10-minute circuit of
gymnastic-type moves performed as quickly as possible. And finally, two to 10
minutes of high-intensity sprint training. Incorporated into the mix is jump
training, obstacle courses and lifting and swinging various heavy objects like
kettlebells (weighted balls with handles). The whole thing takes about 20
minutes

Key words in that paragraph: high-intensity. Possible side-effects: nausea or death. So far just a little nausea.

Here's an example. I'm using lighter weights, though.
