Move gently and stop if you feel sharp pain, dizziness, numbness, or symptoms that feel unsafe. This routine is general fitness guidance, not medical care.
Exercises
1. Dumbbell Single Arm Row
3 sets 路 10 reps 路 60s rest 路 both sides
Support the free hand on a bench, keep the hips square, and row to the hip rather than the shoulder.
Steps
Place one knee and the same-side hand on a flat bench with your back parallel to the floor.
Hold a dumbbell in the opposite hand with your arm hanging straight down beneath your shoulder.
Set a flat back, brace your core, and keep your hips square to the bench.
Pull the dumbbell up to the side of your ribs by driving your elbow back along your body.
Squeeze your shoulder blade in toward your spine at the top of the row and pause briefly.
Lower the dumbbell slowly until your arm is fully extended again, then repeat for reps before switching sides.
Cues
Brace on support.
Elbow drives back.
Keep hips square.
Common mistakes
Rotating the torso to throw the dumbbell up, which turns the row into a swing and offloads the back.
Pulling with the arm only and letting the elbow flare wide, which trades lat work for rear-shoulder work.
Rounding the lower back instead of bracing flat, which puts the spine at risk under load.
Cutting the bottom range short and skipping the lat stretch, where most of the growth stimulus happens.
2. Dumbbell Upright Row
3 sets 路 12 reps 路 60s rest
Pull the dumbbells up close to the body and stop below chest height. Elbows lead, wrists stay relaxed.
Steps
Stand tall with a dumbbell in each hand resting in front of your thighs and palms facing your body.
Set your feet shoulder-width apart with knees soft and core lightly braced.
Keep your chest up and your shoulders pulled back and down before starting the pull.
Pull both dumbbells straight up along the front of your body by leading with your elbows.
Stop the pull when your elbows reach about chest height, with the dumbbells just below your collarbones.
Lower the dumbbells slowly back down along the same path until your arms are fully extended.
Cues
Elbows lead up.
Stop at chest height.
No shrugging.
Common mistakes
Pulling the dumbbells higher than the collarbones, which can cause front-shoulder strain at the top.
Using too much weight and swinging the body to throw the dumbbells up, which removes the shoulder work.
Letting the elbows drop below the wrists, which turns the pull into a curl instead of a row.
Rounding the upper back during the lift, which removes the upper-trap engagement.
3. Dumbbell Laying Reverse Fly
3 sets 路 12 reps 路 60s rest
Lying face down isolates the rear shoulders completely. The range is small on purpose.
Steps
Set a bench to about a 45 degree incline and lie face-down on it with a dumbbell in each hand.
Let the arms hang straight toward the floor, palms facing each other, with a slight bend in the elbows.
Brace the core, plant the toes on the floor, and lock the slight elbow bend for the set.
Open the arms out to the sides in a wide arc, leading with the elbows toward the ceiling.
Squeeze the rear delts and the middle of the back together at the top of the lift, pausing briefly.
Lower the dumbbells under control over 2 to 3 seconds back to the hanging start position.
Cues
Face down.
Small lift.
Neck stays long.
Common mistakes
Bending and straightening the elbows mid-rep, which sneaks the triceps and traps into the lift.
Pulling the dumbbells back like a row, swapping rear-delt isolation for mid-back rowing work.
Shrugging the shoulders up at the top, which trades rear-delt work for trap engagement.
Loading too heavy, which forces swinging form and removes the strict isolation the bench enforces.
4. Dumbbell Seated Rear Delt Fly
3 sets 路 12 reps 路 60s rest
The rear shoulders are usually the weak link after desk work, so keep this light and precise.
Steps
Sit on the edge of a bench with a dumbbell in each hand and your feet planted shoulder-width apart.
Hinge forward from the hips until your chest is close to your thighs and your arms hang straight down.
Keep a small bend in the elbows and palms facing each other, with the dumbbells underneath your shoulders.
Raise both dumbbells out to the sides in a wide arc until your upper arms are parallel to the floor.
Squeeze your shoulder blades together at the top and feel the rear shoulders working.
Lower the dumbbells under control along the same arc and reset before the next rep.
Cues
Hinge forward.
Lead with elbows.
Squeeze the back.
Common mistakes
Using too much weight and swinging the torso, which turns the lift into a row instead of a fly.
Bending the elbows and pulling instead of keeping a fixed angle and lifting from the rear shoulders.
Shrugging the shoulders up at the top, which transfers the work to the upper traps.
Sitting upright instead of hinging forward, which lets gravity bypass the rear shoulders entirely.
5. Dumbbell Shrug
3 sets 路 12 reps 路 60s rest
Shrug straight up toward the ears and pause briefly at the top. No rolling the shoulders backward.
Steps
Stand tall with a dumbbell in each hand at your sides and your feet shoulder-width apart.
Let your arms hang straight down with palms facing your thighs and core braced.
Keep your chest up, chin neutral, and shoulders relaxed in the starting position.
Shrug your shoulders straight up toward your ears as high as they will go without bending the elbows.
Pause and squeeze the traps hard at the top of the shrug for one full second.
Lower the dumbbells back down under control and feel the stretch before the next rep.
Cues
Arms stay long.
Lift shoulders up.
Lower with control.
Common mistakes
Rolling the shoulders forward or backward, which adds joint strain without making the lift more effective.
Bending the elbows during the lift, which turns the shrug into a partial pull and reduces trap work.
Bouncing into the bottom of each rep, losing tension and bypassing the trap stretch.
Going too heavy and barely moving the dumbbells, which leaves the traps under-stimulated.
6. Dumbbell Curl
3 sets 路 10 reps 路 60s rest
Keep the torso still and the elbows at your sides so the biceps do the work, not the shoulders.
Steps
Stand tall with a dumbbell in each hand at your sides, palms facing forward.
Set your feet shoulder-width apart, brace your core, and pull your shoulders back and down.
Curl both dumbbells up toward your shoulders by bending at the elbows, keeping the upper arms pinned to your sides.
Squeeze the biceps hard at the top with the dumbbells close to your shoulders for a brief pause.
Lower the dumbbells slowly to full arm extension over 2 to 3 seconds.
Reset at the bottom with the arms straight and the shoulders set, then repeat for reps.
Cues
Elbows stay pinned.
Lower slowly.
No swinging.
Common mistakes
Swinging the torso back to throw the dumbbells up, which removes the biceps from the lift.
Letting the elbows drift forward on the way up, turning the curl into a partial front raise.
Cutting the range short at the bottom by never fully straightening the arms between reps.
Dropping the dumbbells fast on the way down and skipping the slow lowering phase where most growth lives.
7. Dumbbell Hammer Curl
3 sets 路 10 reps 路 60s rest
Neutral grip with the palms facing in. Curl without swinging and lower over about two seconds.
Steps
Stand tall with a dumbbell in each hand, arms at your sides, and palms facing your thighs.
Keep the elbows pinned to the ribs and the shoulders pulled back and down throughout the set.
Curl both dumbbells up by bending only at the elbow, keeping palms facing each other the whole time.
Squeeze hard at the top with the dumbbells just below shoulder height and the wrists locked straight.
Lower the weights under control over 2 to 3 seconds back to a fully straight-arm position.
Pause briefly at the bottom with the elbows extended, then curl back up for the next rep.
Cues
Elbows stay close.
Wrists neutral.
Lower slowly.
Common mistakes
Swinging the torso to throw the weight up instead of curling cleanly with the arms.
Letting the elbows drift forward at the top, which turns the curl into a half front raise.
Rotating the wrists at the top and rushing the lower, missing the brachialis-building tension.
Using too heavy a weight, which forces partial reps and short-changes the muscle stretch.
8. Dumbbell Incline Curl
3 sets 路 12 reps 路 45s rest
Lying back puts the biceps under a longer stretch, so start lighter than your standing curl.
Steps
Set a bench to about a 60 degree incline and sit back with a dumbbell hanging from each hand.
Let the arms fully extend straight down, palms facing forward, and pull the shoulder blades back into the bench.
Keep the elbows pinned at your sides and resist letting them swing forward as you start the rep.
Curl both dumbbells up by bending at the elbow only, squeezing the biceps as the weights rise.
Stop the curl just shy of the elbows traveling forward, then squeeze hard for a brief pause at the top.
Lower the dumbbells under control over 2 to 3 seconds back to the fully stretched bottom position.
Cues
Arms hang back.
Full stretch low.
Squeeze at the top.
Common mistakes
Letting the elbows drift forward at the top, which removes the long-head stretch the lift is designed for.
Rolling the shoulders forward off the bench, swapping biceps work for front-shoulder strain.
Rushing the lower portion and skipping the stretched bottom where most of the growth comes from.
Going too heavy, which forces a swinging cheat curl and loses the strict isolation.
