As is the case with any muscles at the back of our bodies, the calves tend to be forgotten. It's the age old "out of sight, out of mind" scenario.
So I'm glad you're here, because calf raises give a great toned shape to any kind of legs. Not only that, your calf muscles (gastrocnemius and soleus) attach to the achilles tendon, so strengthening them plays an important role in protecting you from injury.
Added to all of that, strong calf muscles will give you a boost to your performance in activities like running, jumping and cycling.
If you're one of the many people who have large calves, and are upset because they look out of proportion, well there's 2 probable reasons for this.
The 1st is that we all have different body shapes, and you may have naturally large calf muscles. Unfortunately there's not much that can be done to make them smaller. The positive is that your other muscles should be in proportion, so hopefully your calves won't look out of place.
The common myth is that large muscles are strong muscles, that's not always true if you have naturally large muscles. Strengthening and toning them will not only protect you from injury, but also make your calves look more streamlined and not so bulky.
The 2nd reason is that you have fat covering your calf muscles. I often get complaints about "flabby calves", and that calf raises don't work for them.
Actually the calf raises are working just fine in making the calf muscles stronger, but they won't do much to burn fat above the muscles.
So the answer is to do
fat burning exercises
that'll quickly burn your overall body fat. You'll end up with the best fat-free, toned calves. Motivation or what!
