seeking stronger calves

I train my calves quite a lot (ballet 3 days/week-which is very calves intensive with pirouettes and such; usually do some calves stuff-calf raises with bodyweight and on a leg press-at least once/week at the gym), but strength gains are pretty slow-particularly in my non-dominant side (left). :bang: Got any advice on getting stronger calves?



Thanks!

Best regards,

Matvei.
