Range in every direction plus the first soleus-specific hold — the muscle that carries running.
The soleus takes several times body weight with every running step — more than any other muscle in the leg.
With the knee bent past about 20°, the gastrocnemius slackens and the soleus does the work. Straight-knee raises miss it.
A stiff ankle changes how the foot lands and shifts load up the chain. Range work is part of shin rehabilitation.
Three couplets · two rounds · twelve minutes · legs that take the miles
Draw the biggest slow circle the ankle allows — thirty seconds each direction.
Easier smaller circles · Harder slower and bigger
Back to a wall in a shallow squat, heels lifted; hold on the toes with the knees bent.
Easier heels lower · Harder deeper squat
Roll a ball slowly up and down the calf, pausing where it is tender but tolerable.
Easier less pressure · Harder more pressure
Heels down; lift the toes and forefoot as high as possible, lower over three seconds.
Easier smaller range · Harder hold two seconds
Draw the alphabet in the air with the big toe — count the letters completed.
Easier capitals only · Harder slower and larger
Face down, knee bent 90°; point the foot hard and squeeze the calf for five seconds.
Easier gentler squeeze · Harder 8-s holds
Each couplet: 60 s scored → the loading set → 10 s to move on. Done at 12:00.
