Phase 1 check-in: measure the ankle range, take a full heel raise, and walk on the toes and the heels.
A healthy adult should manage in the region of 25 single-leg heel raises through full range. Most people cannot.
Plantarflexor strength is the biggest single contributor to walking speed, and walking speed tracks with independence in later life.
The final push of every step comes from the calf and big toe. Weak there and the whole stride shortens.
Three couplets · two rounds · twelve minutes · feet that carry you
Measure the furthest the toes can be from the wall with the knee still touching, then work there.
Easier closer · Harder further back
All the way up onto the toes, pause one second, all the way down under control.
Easier hold a support · Harder 3-s lowering
Walk on the balls of the feet with the heels high — count the steps.
Easier hold a support · Harder slower and higher
On one foot; lift the arch without curling the toes and hold, three points down.
Easier two feet · Harder eyes closed
Walk on the heels with the toes lifted clear of the floor — count the steps.
Easier shorter distance · Harder slower and higher
Seated, a heavy bag on the knees; lift the heels and lower slowly. Knee bent loads the soleus.
Easier no weight · Harder heavier
Each couplet: 60 s scored → the loading set → 10 s to move on. Done at 12:00.
