The Claim

Modifying foot alignment during unilateral calf raises selectively stimulates specific heads of the gastrocnemius muscle, with outward positioning preferentially enhancing medial head hypertrophy and inward positioning preferentially enhancing lateral head hypertrophy, thereby enabling region-specific muscle growth in resistance training.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Changing the way you point your feet while doing calf raises can target different parts of your calf muscle. Pointing your toes outward mainly builds the inner part of your calf, while pointing them inward mainly builds the outer part. This gives you a simple way to shape your calves exactly how you want them.

See the scientific wording

Adjusting foot alignment during unilateral calf raises allows for selective stimulation of specific gastrocnemius muscle heads, as outward positioning preferentially enhances medial head growth while inward positioning preferentially enhances lateral head growth, providing a practical method for region-specific hypertrophy training in resistance exercise programs.

What the research says

1 study
  1. Study: Different Foot Positioning During Calf Training to Induce Portion-Specific Gastrocnemius Muscle Hypertrophy.

    Changing the direction your feet point while doing calf raises can actually target different parts of your calf muscle. Pointing them out grows the inner calf more, while pointing them in grows the outer calf more.
