Q: What are the best exercises                        for increasing calf strength and size? I do a lot of standing                        and seated calf raises, but I was wondering if there is                        anything else I’m missing? I’m about 2”                        away from dunking a basketball and I’m looking for                        an edge. Any advice you can give me would be greatly appreciated.

                      A: Big calves have about                        as much to do with how high you can jump as the color of                        your hair. Sure, there’s nothing wrong with doing                        some calf raises in your training routine, but they shouldn’t                        be the 
focus of the routine. As I’ve said                        time and time again, the “posterior chain” (spinal                        erectors, gluteals and hamstrings) makes up around 70% of                        the musculature that is responsible for your jumping ability.                        Squat and deadlift variations, Olympic lifts and good mornings                        will give you the best “bang for your buck”                        with regards to improving your vertical jump in the weight                        room. 
                     There is another very interesting factor                        that plays a large role in how high you can jump. I’ve                        had the pleasure of working with over 2-dozen athletes who                        can jump over 35” and, besides being very strong in                        the posterior chain, they had something else in common.                        The one thing they all had in common are what I call “high                        cut” calves. What I mean by this is that the calves                        have an insertion point very high on the lower leg. This                        usually means a longer Achilles tendon. A longer Achilles                        tendon can store more elastic energy, which translates into                        more explosive jumps. 
                     Think about this; have you ever seen a                        kangaroo with big calves? Of course not! The reason they                        can jump so well lies in the length of their Achilles tendons.                        Kangaroos have the longest Achilles tendon of any animal                        on earth. They also spring off the ground better than any                        other animal on earth. Unfortunately, you can’t increase                        the length of your Achilles tendon – it’s genetic.                        You have your parents to thank for that.
