Muscle Mechanics: A New Twist for Awesome Arms

Q: I have learned an incredible amount from your X Arms e-book. My question has to do with emphasizing the biceps heads. You suggest total focus on one head at each workout. Instead, I want to use two sets in each position of flexion, with each set focusing on a different head. For example, for the first exercise (midrange), I’ll do one set of close-grip preacher curls for the outer biceps heads; then follow with one set of wide-grip dumbbell curls for the inner heads. I’ll do that for the stretch-position exercise and the contracted position exercise, using the specific movements in your e-book, one set for each head in each position. I plan to use that biceps routine every arm workout. I’ll use the same two-sets-for-each-position idea for triceps too. What do you think?

A: Let’s see, two sets in each of the three positions of flexion, one set for inner-head emphasis, the second for outer-head emphasis. Interesting. That’s a different strategy from what we outline in X-traordinary Arms, which is to focus on one head of the biceps at one workout, then focus on the other head at the next to build awesome arms.

Muscle Mechanics for More Calf Mass

Q: I picked up your 10×10 e-book over the weekend and started using that style of training on calves immediately, but I’m doing 8×20 as you’ve suggested in the e-book. My question is, should I angle my feet differently on each set to develop the most calf mass? I was thinking toes in on the first three, toes out on the second three, and toes straight ahead on my last two sets.

A: It’s not foot angle that stresses the inner or outer heads of the gastroc, but rather which side of the foot you’re exerting the most pressure with. In other words, if you’re pushing with the inner part of the ball of your foot, the big-toe side, you will stress the inner head of the calf muscle. If you roll out onto the little-toe side of your feet as you rise, you will stress the outer head of the calf muscle.

Notice in this photo how the trainee is using a narrower stance and rolling out; that’s not what you want. Go wider than this for more calf mass…
