What does this word mean in the sleeve (or nutrition/fitness?) community?

I've never heard of it, but according to wiki: http://en.wikipedia.org/wiki/Hitting_the_wall

The term bonk for cycling fatigue is presumably derived from the original meaning "to hit", and dates back at least half a century. A 2005 video issued by the British Transport Films Collection contains several old films, one of which entitled "Cyclists Special", a color film produced in 1955, tells the story of a party of cyclists touring the English countryside. At one point they stop for refreshments and the film's commentator states that if they didn't rest and eat they would get "the bonk".^[1]

The term is used colloquially both as a noun ("hitting the bonk") and a verb ("to bonk halfway through the race"). The condition is also known to long-distance (marathon) runners, who usually refer to it as "hitting the wall". The British may refer to it as "hunger knock," while "hunger bonk" or "bunger honk" was used by South African cyclists in the 1960s.

Okay, I see. Thanks.

How about bonking on the last rep of a lift?

OMG....I was thinking the same thing!! LOL

From what I've seen, read and experienced bonking is when your body runs out of glycogen (sugar) to burn as fuel and switches over to burning fat. The switch over in the middle of a hard exertion like exercise is not very efficient and your body sends you signals to stop what you're doing....basically it makes you feel very weak and shitty. That's what happens to runners and cyclists quite often but it can happen to anyone doing any kind of long sustained exercise and it is not pleasant.

Interestingly, the more you work on burning fat for fuel instead of glycogen the less opportunity you have for this to happen. The body can get better at anything just by practicing it. I've been trying to keep my workouts in a fat burning zone for several months and have not bonked one time.

No girls....

I mean the last lift of a set of weight lifts. This is where I bonk, where I am praying for the nitro fairy to give me something, anything to finish that rep.
