Usually I do calf stretch against a wall like this image:

Instead of pushing one leg backward as in the above image, I am thinking about pushing both legs to stretch both calves simultaneously somehow like this image:

When I tried it, I found that it also incorporates probably the whole posterior chain in addition to the hands. So basically I think it is probably better. But I am not sure, that is why I ask.
What are the pros and cons of pushing both legs simultaneously while doing calf stretch against a wall?
Thank you.
