Roll With the Waves

Most grapplers either go hard every session until their body forces them to stop, or they vaguely "take it easy" some days without any real structure behind it. Both approaches leave serious progress on the table.

Pavel Tsatsouline’s Delta 20 principle offers a smarter framework, and it translates to BJJ surprisingly well.

The idea is simple. Undulate your training across three types of days: heavy, medium, and light. The key is that each wave must represent a meaningful change of at least 20 to 25 percent in either volume, intensity, or both.

Say your heavy day is 6 to 8 rounds of hard sparring. A medium day would mean 4 to 5 rounds at an honest but not murderous pace. A light day drops further still to maybe 2 or 3 rounds, where you're problem-solving rather than competing.

Why does this matter?

BJJ has a way of disguising cumulative fatigue, where you feel fine, right up until you don’t, and in a sport that rewards those who show up consistently over years, that’s a problem.

Heavy days are where you test yourself. Medium days, when you're sharp but not gassed, are where most skill acquisition actually happens. Light days keep the movement patterns dialled in without adding to your total fatigue.

The wave gives you a structure so your body knows when to push and when to recover so that your sessions don't blur into one undifferentiated grind.
