BEST BICEPS ISOLATION MOVE LYING CABLE CURL KNEE-JERK REACTION “You know the dumbbell concentration curl exists, right?” OUR EXPERTS’ TAKE “The cable curl is similar to a concentration curl in that momentum can be eliminated, so no other muscle group can assist other than for stabilization,” says Gerren Liles, a Reebok One ambassador and Equinox Master Instructor based in New York City. The slight edge goes to the cable, however, because the resistance remains steadfast throughout the movement—unlike with a dumbbell, where the stimulus can dissipate at the bottom or even the top of a movement without careful attention to positioning. HOW TO DO IT Q Attach a short straight bar to a seated cable row station and lie down, feet placed firmly on the platforms with the cable going between your knees. Hold the bar with a supinated (underhand) grip just inside shoulder width. Q Keeping your elbows at your sides, bend your arms to curl the bar all the way toward your chin, holding the peak contraction for a moment. Q Lower the bar back along the same path under control. INTENSIFY IT Dropsets are a killer pairing with cable movements because it’s so simple to lower the weight each time you hit failure. 92 FLEX | MARCH ’18 BEST BICEPS MOVE FOR MOUNTAINOUS PEAKS EZ-BAR PREACHER CURL KNEE-JERK REACTION “Doesn’t the incline curl hit the long head better?” OUR EXPERTS’ TAKE As mentioned earlier, the long head of your biceps is most responsible for the “peak” you see when you flex your arms. And with your arms behind you, as with an incline dumbbell curl, the long head is put under stretch to start, which leads to a stronger contraction. So why does Roberts like EZ-bar preachers just a bit better when it comes to reaching your developmental “peak”? “EMG activation studies do show better biceps activation for incline curls than preachers, at least through the first two-thirds of the movement,” he says. “But that’s just one part of the whole picture. Other variables are more important to growing the long head, like the amount of weight you can handle and the intensity you can put into the exercise. The preacher wins on both counts.” Use the inner grip of the EZ-bar, remembering that a narrow grip will help target the long biceps head. HOW TO DO IT Q Adjust a preacher bench so that the top of the pad fits securely under your armpits. Take an inside-shoulder-width, underhand grip on the EZ-curl bar— KEY POINTERS “Press your midback and lower back into the bench and brace your abs,” Liles instructs. “Also make sure you have a wide enough handle where your hands are in line with your elbows—and work through a full range of motion. Your legs should be positioned so that they leave room to straighten your arms out completely.”
