Nate

Possibly one of the barriers that CrossFit faces is that people look at the workouts and cannot begin to fathom actually how to do the workouts. We look here at "Nate" a heroes wod, and see 2 muscle ups, 4 handstand pressups, and 8 32 kg kettlebell swings for as many rounds as possible for twenty minutes.
The issues we face with the wod is what elements of the workout to scale, according to the ability of the client whilst still maintaining the intensity.
The further issue is that the muscle up is a major gymnastic movement, comprising of a pullup and a dip performed on the rings, and is, in itself a major achievement for most CrossFitters.
We would scale this, ordinarily with a ratio of 4 to 1. 4 pullups and 4 dips as the equilavalent to 1 muscle up.
Using this theory we would see the the wod as:
4 pullups
4 dips
4 handstand pressups, again scaled, as we see in the first and second pictures, using a box or walking up the wall to aid the movement.
8 swings.
The question that this form of scaling raises is that is the intensity of the wod comprised, would it be better to drop a movement of the wod and introduce a monostrutural element in order to maintain intensity, again this depends on the abilities of the client and the level of intensity we wish for.
For some it would prove constructive, for other less so.
Alex did it pretty much as RX'd.
