This four-move bicep workout will help you build bigger, stronger arms

If you're after visually impressive muscle, working your biceps is the best place to start. You don't have to aim for bulging arms, but this t-shirt friendly muscle looks good but has some important functional benefits, too. 

You may already be using the best bicep workouts to develop your upper arms. But, if you're looking to add some variety to your exercise schedule, this four-move routine from Jason Bone, Head of Strength at FLEX Chelsea, will work your biceps and develop more muscular arms in no time. 

Many bicep moves are performed one arm at a time, but this may benefit your static arm too. Interestingly, a recent study found that exercising a single arm can improve strength and decrease muscle loss in the other. The best way to target these muscles is to focus on your form rather than worrying about total reps.

According to Jason, "Time under tension is a great way to increase arm size. Rather than counting repetitions, set a timer and try to maintain a slow, steady movement with minimal rest at the bottom of the rep. You definitely don't need to push heavy; just keep the tension in the muscle!"

To get started, you only need a set of the best adjustable dumbbells and a bit of space for your exercise. Perform each exercise for 40 seconds, followed by 20 seconds of rest before starting the next move. Repeat the routine four times for an effective strength-based routine. 

1. Bicep curl

Hold a dumbell in each hand, elbows close to your body, and with your palms facing the sky. Curl the weights up towards your shoulders while squeezing your biceps, then slowly control the movement back down to your start position.

2. Skull crusher

Laying on your back with the dumbbells raised above your head, keep your elbows still and as close to each other as you can. Bend your elbows so the weights move towards your forehead, then straighten your arms back to the original position.

3. Single-arm dumbbell hammer curl

Standing tall, holding a single dumbbell by your side, keep your elbow still and your palm facing inward. Curl the dumbbell up to the shoulder, squeezing the bicep at the peak, then control the movement back to the original position. Repeat for the move for the other arm. 

4. Tricep kickback

With a dumbbell in one hand, palm facing towards your body, bend slightly forward, hinging at your hips. Keep your elbow bent and by your side, fully extend your arm out until straight behind you and squeeze the tricep, slowly bring the arm back to the start without moving the elbow. Repeat for the move for the other arm.
