Most of us do some form of S and C work in addition to our martial arts, but how do we know our work is actually improving our strength and conditioning? What measurements are you using to judge your programs effectiveness? If I ask that of most guys the answer is easy for strength and hard to judge for conditioning, they say my 1 rep max has gone up, I can do more reps with the same weight etc when it comes to strength but when It comes to conditioning the answer is usually I can last longer on the mats or in the ring, but that is subjective and can be down to other matters than your conditioning program such as skill efficiency and better energy conservation. People would never go to the gym and lift weights blindfolded so they had no idea what was on the bar day in or day out, or without some way to measure progress but this is frequently what happens when it comes to conditioning. If you aren't using a simple heart rate monitor, if you aren't measuring resting HR, heart rate recovery, power output at threshold, true max heart rate, or things like distance covered during timed sessions, number of reps completed in a fixed time period how can you expect to make measurable progress?
