http://www.amazon.com/Trained-Sports-Resistance-Exercise-Crossfit/dp/B00F88IIGM/ie=UTF8?m=A1EPX82UT8VPGG&keywords=resistance+bands Tricep muscles are comprised of 3 heads: lateral head, long head, and medial head - therefore the TRI in triceps. Focus your triceps more accurately by maintaining your wrists straight and elbows rooted in a fixed position with your upper arms still. Continue to keep consistent tension on the resistance bands by not going over the minimal point of resistance so that your muscles don’t get a break till after the set. During your set, take some time and contract your triceps for a couple moments at the point of optimum resistance before coming back to the starting position. Last but not least, keep your ab muscles tight and back straight to safeguard and strengthen your core.
