One-Arm Dumbbell Row
Training one arm at a time with this move proves unparalleled for growth. Because you can use a little body english, you can actually recruit more muscle fibers and generate more force than when using both arms simultaneously in the barbell bent-over version.
Do it Right: Lean forward at the waist, and place one knee and the same-side hand on a flat bench. Keep your other foot on the floor beside the bench and grasp a dumbbell in the same-side hand, allowing the weight to hang straight down with your arm fully extended. Pull the weight toward your hip, keeping your elbow in close. Pull your elbow as far back as you can, squeezing your shoulder blades together for a full contraction, then lower the dumbbell along the same path. Repeat for reps, then switch arms.
Power Pointer: A common mistake is to bring the dumbbell straight up to the shoulder. However, the best line of pull is up and back toward your hip. That provides a greater range of motion and time under tension for the stubborn lower lats.
Flat-Bench Dumbbell Press
This multijoint chest exercise is a proven mass-builder. Although you’ll quickly discover if one side of your pecs is stronger than the other, you get a longer range of motion over the barbell version because you can press both up and in rather than just up.
Do it Right: Lie faceup on the bench with your feet flat on the floor. Grasp a dumbbell in each hand just outside your shoulders. Powerfully press the weights up and together, stopping when they’re an inch or so away from touching. Slowly return to the start.
Power Pointer: Don’t let the dumbbells touch at the top, because you’ll release tension on the pecs and start getting into the habit of resting briefly at the top of each rep. Leave a few inches between the weights so your pecs don’t get a chance to relax.
Seated Overhead Dumbbell Press
Because you don’t have a bar in your hands, you can draw your elbows all the way back outside your ears. That places more emphasis on the middle delts, the one delt head that makes you appear wider. In contrast, with a barbell your elbows have to travel forward so the bar clears your face, calling upon more front delts than middle delts. Do it Right: Adjust the bench so your back is fully supported and upright, and grasp a dumbbell in each hand above shoulder level with a pronated grip (palms facing forward). Strongly press the weights overhead in an arc, but don’t let them touch at the top. Lower under control back to the start. Power Pointer: Don’t stop the downward motion when your arms form 90-degree angles; instead, bring the dumbbells all the way down until your elbows point toward the floor and the weights are just above shoulder level. It’s safe for your shoulders, and you recruit more muscle fibers when using this greater range of motion.
Dumbbell Shrug
The range of motion here is only a few inches. The up-and-down movement should be fluid and controlled, not explosive. Because you’re using dumbbells, the neutral (palms-in) grip helps keep your arms and shoulders in the most comfortable and safest position possible. Do it Right: Stand erect holding a dumbbell in each hand at your sides with your palms facing in. Keeping your chest up and abs tight, shrug your shoulders straight up toward the ceiling, squeezing your traps at the top. Slowly reverse the motion, letting the weights lower your shoulders as far as possible. Power Pointer: Avoid rolling your shoulders — it doesn’t engage the upper traps more successfully and can actually cause severe strain of the delicate rotator-cuff muscles. Keep the motion strictly up and down.
Seated One-Arm Overhead Dumbbell Extension
With your arm overhead, you’ll better engage the largest and most dominant muscle on the back of the arm, the meaty long head of the triceps. That’s true no matter what kind of equipment you use — cable, barbell or dumbbell. Do it Right: Sit erect on an upright bench, feet flat on the floor. Grasp a dumbbell and hold it overhead at full arm extension. Bending only your elbow, lower the weight behind your head until your arm forms a 90-degree angle. Feel your triceps stretch, then press back up to full-arm extension and squeeze your tri’s hard at the top. Repeat for reps, then switch arms. Power Pointer: Try the two-arm version, too, but keep your elbows in tight. Allowing them to flare out wide reduces the muscular stress on the triceps.
Alternating Dumbbell Curl
Unlike the barbell curl, the alternating dumbbell curl allows you to perform what’s called supination at the top of each rep. Starting with a palms-in (neutral) grip, you can slowly turn your wrists as you approach the top of the move, and that twisting motion allows for a better peak contraction and overall growth.
Do it Right: Stand erect holding a dumbbell in each hand at your sides. Keeping your chest up and elbows in tight, curl one weight toward the same-side shoulder, turning your wrist up as you go. Squeeze your biceps hard at the top, then lower to the start. Repeat with the opposite arm.
Power Pointer: Of all the ways to perform this movement wrong, the most common is to try to bring the weight as high as possible, which pulls your elbow away from your side. However, this recruits the front delts and lessens the isolation on the biceps. Keep those elbows back!
Dumbbell Wrist Curl
The wrist curl goes last, and that’s no accident. If you hit your forearms too early in your workout, they’ll fatigue and prevent you from maintaining a good grip when training larger muscles like the back and biceps. This puts those bodyparts at a disadvantage because they rely on the forearms to be fresh.
Do it Right: Sit at the end of a bench with your forearms flat on it, and grasp a dumbbell in each hand with your palms up. Allow the weights to roll to your fingers, then use your wrists to curl the dumbbells back to the start. Power Pointer: For a greater range of motion and stretch on the brachioradialis, keep your thumb on the same side of the dumbbell handle as your fingers. This ensures that you fully engage as much of the lower forearm as possible.
To build robust shoulders you need to target them from multiple angles to activate all three heads of the deltoid muscle. Dumbbells are the perfect tool for the job. While barbell moves often require a spotter, and most machines fix your movement in one plane of motion, dumbbells require all your stabiliser muscles to work, force your core to hold everything together and offer plenty of versatility with every exercise. This three-part shoulder complex from trainer Tom Dyer puts dumbbells to good use in targeting all three heads of your deltoids, helping you increase and maintain tension on the muscles, starting with the weaker rear deltoids and finishing by hitting all three in one big-hitting lift even Arnold Schwarzenegger would be proud of. Palms-In Shoulder Press Stand up and hold two dumbbells at shoulder level, palms facing each other. Push the dumbbells straight up until your elbows come close to locking and lower them back down after a short pause. Be careful ...

What is testosterone, and how does it work? Testosterone is a powerful steroid hormone that has different functions in both males and females. It allows us to gain lean muscle mass, maintain a healthy body composition, and maintain adequate bone density. Testosterone is found in humans and some other mammals. Males produce testosterone in their testicles. Women's ovaries do contain testosterone, though in lower amounts. The brain and pituitary gland control the amount of testosterone released by the body. It enters the bloodstream after being produced and performs a number of important functions. Testosterone levels increase during puberty and then begin to decline later in their forties. What is the significance of testosterone? Testosterone is essential for good health in addition to helping you have a nice body. Low testosterone levels can lead to a variety of health issues in both men and women, including depression, a lack of sex drive, obesity, and osteoporosis. Men with lo...
