Take a look inside
Here is a preview of one entry from the Movement Foundation Index: Fitness. Every one of the 115 exercises (and all 104 poses in the Yoga Index) is written with this depth, and the preview shows only part of the entry.

Movement Foundation Index: Fitness, preview
Calf Raise (Seated or Standing Heel Raise)
At a glance
- Plain language: Lifting your heels and lowering them back down, seated or standing
- Category: Lower Body Strength / Ankle and Calf Strength / Balance
- Equipment: A sturdy chair for the seated version. Optional: a wall, chair, or rail for balance, a step or block for extra range, dumbbells or a weight across the thighs.
Detailed sensory description (excerpt)
Seated: “You press the balls of your feet into the floor and lift your heels as high as you can, exhaling. You feel the lower part of your calf, deep under the bigger muscle, working. Your pressure stays over the base of the big and second toes.”
Standing: “You press down through the balls of your feet and lift your heels, rising as high as you can control. You feel the backs of your lower legs tighten and work. Your weight stays over the base of the big toe and second toe, rather than rolling out to the little-toe side.”
What you should feel (excerpt)
- Strong engagement in: Gastrocnemius (upper calf muscle) and Soleus (deeper, lower calf muscle)
- Throughout the movement: weight centred over the base of the big and second toes; slow, smooth lowering
Teaching scripts (in full)
Seated
“Sit tall in a sturdy chair, or with the brakes on your wheelchair, feet flat and hip-width apart.
Rest a weight or your hands on your thighs.
Press through the balls of your feet and lift your heels.
Pause at the top.
Lower your heels slowly to the floor.”
Standing
“Come to standing, feet hip-width apart.
Rest your hands on a support if you like.
Press through the balls of your feet and rise up tall.
Pause at the top.
Lower your heels slowly back to the floor.”
Adaptive variations (excerpt)
- Amputees and limb differences, with a prosthesis: “Most prosthetic feet do not point actively, so the sound calf does the lifting while the prosthetic foot stays flat and shares some weight; this is a full version”
- Larger bodies: “Lead with function: strong calves support walking, stairs, and balance”
Also in the full entry (not shown in the preview)
- The complete sensory descriptions for both versions
- What you should not feel
- Adaptive variations for wheelchair users in the chair and on the mat, amputees and limb differences (upper and lower limb, with and without a prosthesis, residual limb care), larger bodies, shorter bodies, neurodivergent participants, and people living with chronic pain or mobility limitations
- Muscles engaged
