Q: How do you feel about one-arm and one-leg work? I’ve read that training one side at a time can help you contract more muscle fibers. Is that true?
A: We’ve seen studies that show unilateral work to be better at neuromuscular stimulation and therefore heightened muscle-fiber activation. Our main problem with one-limb exercises is time and energy expenditure.
Working one arm or one leg at a time takes
Q: I love [3D Positions of Flexion training]. It makes sense and has helped me bring up my chest and delts with fewer sets. My question is about biceps. For the contracted-position exercise, which is best: one-arm spider curls or concentration curls? Or are they about the same?
A: In the X-traordinary Arms e-book we explain the in-for-out/out-for-in principle. For biceps that means that to focus on the outer head for peak, you use an inner-grip exercise. Concentration curls are about as “in” as you can get… [Read more…]
Q: I love Positions of Flexion. I’ve gained about 10 pounds since I started using it, but one problem I have is biceps. I just don’t feel the last exercise for contraction, concentration curls. I’ve tried them Arnold style, with my arm hanging free, and I’ve also tried them seated with my arm against my inner thigh. Is there another exercise I can use?
A: We usually suggest spider curls, which are basically preacher curls on the vertical side of the bench… [Read more…]
Q: I’ve been on the basic Positions-of Flexion biceps and triceps routines you outline in 3D Muscle Building. I’m getting spectacular pumps, and I think my arms have grown already. I’m ready to go to all the POF routines in 3D for all my bodyparts. My question is on biceps. I don’t really feel concentration curls. Is there another ending [contracted-position] exercise I can do instead to help build 3D arms?
A: For the uninitiated, Positions of Flexion is training each bodypart through its full range. For example, for biceps, it’s barbell curls (midrange), incline curls (stretch), and concentration curls (contracted). [Read more…]
