Calves

They aren't the most important muscle group in regards to baseball, but you shouldn't neglect them. There are two different muscles in the calf. Each is worked differently, so include standing and seated exercises. I like to do the standing calf raise machine and the seated plate-loaded calf raise, often known as the donkey calf raise.

i feel like the calves are fairly important. because they have a lot to do with speed.

Strength shoes are the best thing for calves in my opinion i walk around my house in 'em 3 times a week i love them.

Working the calves is not all that important, BUT working the ankles is important as this is a common injury site for ballplayers. If you could do something sideways for your ankles that would be good also.

Actually the calves are fairly important as they used all the time in explosive movements and gives you that quick first step. Calf raises will give them some strength but the first step quickness comes from plyometrics and medicine ball drills.

Tim,
What kind of exercises for "somthing sideways for ankles"? Do you mean kareoke(?) running drills or somthing with weights? What about ankle weights are they of any value?

I don't know what Kereoke running drills are.
Something sideways for the ankle could be isometric,using therabands (or tubing),cables, or manual resistance (like grabbing your foot with your hand and moving it sideways). When you are doing enough running, etc. then calf raises may be redundant. I increased my calf size in high school by doing sprints on the track team not lifting weights.
Ankle weights will not strengthen the ankles other than what comes from the increased collision forces with the ground. Many get injured by them. I think that they are OK if you don't go too heavy and work your way into using them.

Jumping rope is great for calves and cardio too.

Calves are what you use for acceleration and a major part of running (obviously, they are in your leg). Calf raises, and just plain running are the best ways I know to get them stronger.

I forgot one exersise, and it is creative and actually directly related to baseball... try holding the catchers position for while (try 5 mins).

I am glad jumping rope was mentioned. Not only does the jump rope work the lower legs, but it will help foot work which is so crucial to success on the diamond. In addition the jump rope serves as a tremendous conditioning tool.

The calves are important but are not all that crucial to speed. Hamstrings, glutes and lower back have a much greater impact on speed.

Again, overall balanced development is needed to build an athlete that not only performs well but stays healthy.

Where can you buy a good jumprope? I looked and I cannot find one up here. Keep in mind that the only sports store in Alaska is Sports Authority. Thanks for the help, and maybe put a webpage or something.

I like Buddy Lee jump ropes. Do a google search I'm not exactly sure about the website.

I would advise against the weighted ones as well.
