This exercise treats comfort as the governing constraint rather than pursuing a maximal stretch. Lie on your back with both knees bent, place one ankle across the opposite lower thigh to create a figure four, and keep the shoulders relaxed. Move the entire leg shape a small distance to the side, then return to centre. The first range should be deliberately tiny because Tenuto warns against pulling on the sciatic nerve or provoking pain. Only if the small movement feels good should the range increase, first by about ten percent and then perhaps twenty percent. Perform both sides; if symptoms usually favour one side, Tenuto suggests one additional pain-free round there.
Origin
A host asked Tenuto for an exercise for sciatica. Tenuto responded with this floor-based figure-four rock and emphasized small, non-painful progression.
Core principles
- 01Begin below the threshold of pain
- 02Scale range only when the smaller movement feels good
- 03Keep the upper body relaxed and supported
- 04Practice both sides while giving modest extra attention to the more symptomatic side
How to run it
- 1
Build a supported base
Lie on your back with both knees bent toward the ceiling, feet about hip-distance apart, and arms by your sides.
Pro tip Use a surface where your shoulders can relax fully.
Watch out Choose another approach if getting onto or up from the floor is unsafe.
- 2
Form the figure four
Place your right ankle across the lower part of your left thigh while keeping the supporting knee bent.
Watch out Do not force the crossed leg into position.
- 3
Rock the whole shape
Let the crossed-leg shape travel a little to the left and then return to centre. Keep both shoulders relaxed on the floor.
Pro tip Think of moving the shape as one unit rather than pulling on the crossed leg.
Watch out Do not continue into sciatic pain.
- 4
Scale in small increments
If the tiny movement feels good, make the next range roughly ten percent larger and then, if still comfortable, up to twenty percent larger.
Pro tip Let comfort earn a larger range; do not start with it.
Watch out Return to the smaller range or stop if symptoms increase.
- 5
Balance the sides
Repeat the setup and rocking movement on the other side. If one side usually hurts more, add one extra comfortable round on that side.
Watch out Persistent, severe, or worsening symptoms warrant professional assessment rather than repeated self-experimentation.
In the wild
A person whose sciatic discomfort is usually stronger on the right performs a very small figure-four rock on each side. Because neither side produces pain, they repeat the right-side round once, still keeping the shoulders down and the movement small.
→ The more symptomatic side receives extra gentle movement without using a forced stretch.
Common mistakes
Turning the rock into a hard stretch
The exercise uses a small whole-shape rock and explicitly avoids pulling on the sciatic nerve.
Increasing range before comfort
Tenuto makes a good response to the tiny movement the prerequisite for increasing it by ten or twenty percent.
Ignoring the other side
Practice both sides, then optionally give the more symptomatic side one additional round.
Is it for you?
Best for
It is best for someone able to get onto the floor and move through a small figure-four range without pain.
Not ideal for
It is not ideal for acute or worsening pain, neurological symptoms, or anyone unable to use the floor safely.
From the transcript
“You make a figure four position with your leg, which means that your right ankle is um on the bottom of your left thigh.”
“And then you would just take that whole shape and rock it a little bit to your left and come back.”
“you don't want to pull on the sciatic nerve. You don't want to experience any pain.”
