Lying Dumbbell Lateral Raise
side deltoid
What moves the load, and what it costs
3.5MET
பக்க டெல்டாய்டு is the prime mover. Gravity loads the bottom of the range hardest instead of the top, which is the opposite of a standing raise and a useful change of stimulus.
Cue: Lie on your side on a bench or the floor and raise one dumbbell from across the body to vertical.

The compendium files lying dumbbell lateral raise under a category, not a lift. Read the ladder as position, not precision: this is heavier work than sitting quietly by a factor of 3.5, and middling for conditioning work.
Turning that MET value into a real energy cost
- Map the movement to a published category. The compendium measures categories of conditioning work, never individual lifts, so lying dumbbell lateral raise is filed under Resistance training (weight lifting), multiple exercises, 8–15 repetitions at varied resistance.
- Take the category's MET value — 3.5. One MET is the cost of sitting quietly, so this is 3.5 times resting metabolism.
- Multiply by 3.5 to get millilitres of oxygen per kilogram per minute, the unit the MET is actually defined in.
- Multiply by your bodyweight in kilograms and divide by 200. The result is kilocalories per minute of work.
- Count working minutes only. Under load, not under the roof — a set of eight is about 25 seconds of the hour you were there.
kcal/min = MET × 3.5 × body mass (kg) ÷ 200 Lying Dumbbell Lateral Raise: 3.5 × 3.5 × 70 ÷ 200 = 4.29 kcal/min

What is actually doing the work
| Muscle | Role | What it does here |
|---|---|---|
| பக்க டெல்டாய்டுLateral deltoid | Prime mover | Raises the arm out to the side (shoulder abduction) from roughly 15 degrees upward. It is the head that gives the shoulder its width. |
The prime mover produces the movement against the resistance; synergists assist and stabilisers hold a joint still without moving it. An exercise trains the whole muscle it loads — there is no way to work only part of a muscle, and no exercise removes fat from the area around it.
Set up, then earn the rep
Dumbbells, Bench. Every rep should look like the first one. The moment it stops looking like the first one, the set is finished.
PATTERN · ISOLATION
- Stand tall holding the dumbbells at your sides, with a small fixed bend in the elbows.
- Lead with the elbows and raise the arms out to the sides, thinking about pushing away rather than lifting up.
- Lie on your side on a bench or the floor and raise one dumbbell from across the body to vertical.
- Stop at about shoulder height. Higher than that hands the work to the traps.
- Lower slowly — three seconds down is not excessive on this movement.
- Keep the torso still; if it starts swinging, the weight has won.
Where this one breaks down
Not theory. These are the faults you correct on a gym floor, and the correction that actually works.
Swinging the weight up with the whole body.
The side deltoid is small and the lever is long, so the honest weight is embarrassingly light. Use it anyway.
Shrugging at the top.
If the shoulders rise towards the ears, the traps have taken over. Keep them down and stop at shoulder height.
Dropping the weight back down.
Half the available work is on the way down. Lower it slowly.
Regress it, or progress it
Regress — earn it first
Progress — the next demand
Prescription: load, reps, rest
Read off the goal, then hold the technique constant as the load climbs. Derived from the movement's mechanics, not invented for this page: a single-joint movement does its best work in moderate to high reps — very low reps load the joint before the muscle.
| Goal | Sets | Reps | ஓய்வு | Notes |
|---|---|---|---|---|
| Strength | 3–4 | 6–10 | 2 நிமிடம் | Single-joint work responds poorly to very low reps — the joint gets the load before the muscle does. |
| Muscle size | 3–4 | 10–15 | 60–90 வினாடி | This is where isolation work earns its place: cheap volume for one muscle, little systemic fatigue. |
| Endurance / fat loss | 2–3 | 15–25 | 30–45 வினாடி | High reps here are genuinely useful — the load is small enough that form survives the fatigue. |
| First month | 2 | 12–15 | 60 sec | Light. Isolation work is for adding volume later, not for building a base. |
Time under load, in kilocalories
Read these as minutes of work, not minutes in the building. A set of eight takes about twenty-five seconds; the rest of the hour is rest, chalk and queueing.
Mapped category: Resistance training (weight lifting), multiple exercises, 8–15 repetitions at varied resistance — 3.5 MET. That is the published category this movement is filed under, not a measurement of this specific lift.
Worked at 3.5 MET × 3.5 × 70 kg ÷ 200 = 4.29 kcal per working minute for a 70 kg adult. Scale it by your own bodyweight; the equation is linear. The full activity dataset lives at BurnLab.

The questions that come up on the floor
What muscles does the lying dumbbell lateral raise work?
Lying Dumbbell Lateral Raise is a single-joint isolation movement in which the side deltoid is the prime mover. Raises the arm out to the side (shoulder abduction) from roughly 15 degrees upward. It is the head that gives the shoulder its width.
Is the lying dumbbell lateral raise good for beginners?
ஆம். இந்தத் தளத்தில் தொழில்நுட்பச் சிரமத்திற்கு இதற்கு 5 இல் 2 மதிப்பீடு — ஒன்று அல்லது இரண்டு அமர்வுகளில் கற்றுக்கொள்ளக்கூடியது; தவறாகச் செய்தாலும் காயத்தின் அபாயம் குறைவு. மிகக் குறைந்த நியாயமான சுமையுடனும், 12–15 என இரண்டு அல்லது மூன்று செட்களுடனும் தொடங்குங்கள்.
What can I do instead of the lying dumbbell lateral raise at home?
This movement is difficult to reproduce without equipment. Where a bodyweight substitute does not exist, progress by slowing the tempo and using single-limb versions instead of adding load.
How many sets and reps of the lying dumbbell lateral raise should I do?
For muscle size, 3–4 sets of 10–15 with 60–90 sec rest. For strength, 3–4 sets of 6–10 with 2 min rest. In your first month, 2 sets of 12–15, stopping well short of failure. Total weekly hard sets per muscle group matters more than the exact rep number in any of these ranges.
Does the lying dumbbell lateral raise burn fat from the side deltoid?
No. No exercise removes fat from the area it trains — spot reduction has been tested repeatedly and does not happen. Training the side deltoid builds the muscle underneath; where body fat is lost from is decided by an overall calorie deficit and by your genetics, not by which exercise you chose.
Muscle roles follow standard kinesiology references and are described by joint action rather than by gym convention — see how this site is built. Energy figures are derived from the 2024 Adult Compendium of Physical Activities. Every reference is named and dated on the ஆதாரங்கள் page. General information only — not medical or coaching advice. Load, form and progression should be adjusted to your own experience and any injury history. When in doubt, get coached in person.
