This exercise promotes strength of the soleus, the deeper of the main calf muscles.
Progression: add more weight onto the bar, or aim to raise you ankle even higher.
Regression: try the movement without weight, or try it with light weight on your knee (e.g. a small dumbell or a few large books).
Tip: focus on making sure you use your calf muscles and not your hip flexors to move the weight. Aim to use smooth and controlled movement.
