I know a lot of people are against any long slow work but I like to fit one in a week or fortnight because it makes it easy for me to stick to my weight class without starving myself. I also find it's really good stress relief - my meditation I guess.

Apart for that I like to mix it up. I have short intervals like 200m with a break recovery to mimic those really hard short efforts. More of an anaerobic effort. I'll do the equivalent with short, hard fast butterfly sprints in the pool too.

I have longer intervals like 600m and 400m which I do as fast as I can to say mimic one hard steady effort kind of round. I might have a slow jog recovery for this which I think also teaches me that I can recover while still working - maybe as if I've just gone all out but now I'm tired and just moving enough to keep out of trouble and counter.

I have recovery runs which I find help just to keep my legs feeling 'light' and enable me to make better use of the interval sessions. I do find it makes a difference perhaps just because it clears the lactic acid out of those specific running muscles more efficiently than another exercise would.

My club also runs a track in really soft sand near the beach we call the snake pit. It has sand hills and takes about 3 mins to run around. We will do 3 or 4 timed laps.

The trainer's theory is that the variation with hills - the hard uphill efforts and easier downhills mimics the variation you might get within a round depending on how much you and your opponent push each other at different times and whether or not your trying to land big heavy punches or fast snappy counter jabs.
