For home gym owners who want more than a rack and a bar, the RitFit LAM2 Lever Arm Attachment for the M2 Smith Machine adds two independent, adjustable lever arms that turn your all-in-one station into a leverage gym.
This guide covers what the LAM2 is, why it beats a landmine for isolation work, how it changes the resistance you feel, the exercises it unlocks, and a simple 2-day routine. Start light, adjust one variable at a time, and stop any exercise that causes sharp pain.
Quick Answer: The RitFit LAM2 Lever Arm Attachment mounts to the M2 Smith Machine uprights to add two independent lever arms rated for 150 lbs per arm, for a 300 lb total. With a variable pivot height and a guided arc, it lets you press, row, curl, and extend with constant tension and safer failure training at home.
Key Takeaways
- 150 lb per arm: Each lever arm carries up to 150 lbs, for a 300 lb combined ceiling that covers demanding hypertrophy work.
- Variable pivot: Sliding the arms along the M2 uprights changes the force line to match each lift.
- ISO-lateral arms: Each arm moves independently, so a weak side cannot be hidden by the strong side.
- Guided arc: The fixed path removes the dead spots where barbell curls and extensions lose tension.
- Built-in spotter: A fixed lowest point lets you push triceps and pressing to failure without crash risk.
What does the LAM2 lever arm attachment add to the M2 Smith Machine?
The RitFit LAM2 Lever Arm Attachment mounts on the M2 Smith Machine uprights and adds two independent, height-adjustable lever arms. It turns your M2 into an iso-lateral leverage gym where you can press, row, curl, and extend through a guided arc instead of free weights alone.
The LAM2 is built as an M2-specific expansion module, not a generic add-on. Heavy-duty steel construction carries up to 150 lbs per arm, for a 300 lb total ceiling that is plenty for pressing, rows, and arm isolation work.
- Independent arms: Each arm moves on its own, so your weak side has to do the work.
- Adjustable pivot: Set the height to match bench press, shoulder press, rows, or curls.
- Guided path: The fixed arc removes the balance demands of a free barbell.
This is more than enough resistance in practice. Leverage changes how heavy a load feels, so 300 lbs through an arcing path covers near-limit human strength on most isolation movements.

Why use lever arms instead of a barbell in a corner?
A landmine has a fixed pivot on the floor, so every rep follows a long sweeping arc that is great for athletic power but poor for muscle isolation. The LAM2 gives you a variable fulcrum, so you can match the force line to the exact lift you are doing.
Set the pivot at bench height and you get a horizontal push. Set it at shoulder height and you get a vertical press.
| Feature | Barbell in a corner (landmine) | LAM2 lever arms |
|---|---|---|
| Pivot point | Fixed on the floor | Slides along the M2 uprights, locks at any height |
| Bar path | Long sweeping arc from the ground | Matches the lift you are doing |
| Isolation | Better for rotational power than isolation | Clean isolation with a guided arc |
| Symmetry | Both sides share one bar | Independent arms expose and fix imbalances |
Comparison based on the LAM2's published specifications and standard landmine mechanics.
Barbells let your dominant side carry the work. With independent LAM2 arms, the weight only moves when the target arm moves it, which forces symmetry and exposes imbalances that a standard bar hides.
How does a lever arm change the resistance you feel?
A lever arm changes resistance because both the load and the length of the moment arm matter. As the arm travels through its arc, the effective resistance shifts, which removes the dead spots where a barbell curl or extension loses tension.
For a barbell curl, gravity only pulls straight down, so at the top of the rep you are mostly resting the bar on your forearms. On the LAM2, the lever moves on a fixed arc, so you can hold constant tension on the bicep through the full range, similar to a heavier spider curl.
For skull crushers and tricep extensions, the LAM2 acts as its own spotter. The lever arms have a fixed lowest point, so they never crash down on you, letting you push heavy extensions to failure safely.
"The size of the external flexor moment you have to overcome to lift a weight depends on two things: the load itself and the length of the moment arm. This is why lifting heavier weights is harder than lifting lighter weights."

Which exercises can you do with the LAM2?
The LAM2 unlocks pressing, rowing, curling, and leg work that is hard to replicate at home, including chest-supported rows, Viking press, belt squats, and safe tricep extensions. Each movement uses the guided arc and adjustable pivot to keep tension where a free weight loses it.
Why is the chest-supported row a back saver?
Barbell rows put shear force on the lower back. Set an incline bench in front of the M2, grab the LAM2 handles, and row with your chest supported.
This isolates the lats and rhomboids without loading your spine. For more machine-style back work, the LPM2 high row and pulldown attachment for M2 adds cable pulls to the same rack.
Why does the Viking press work so well on lever arms?
A dumbbell press wastes energy keeping the weight stable overhead. With the LAM2 you drive straight up with a guided path, hitting the deltoids with accuracy while letting you add reps.
How does the LAM2 handle belt squats?
Attach a dip belt to the arms and the weight hangs from your hips instead of your shoulders. This lets you train quads and glutes without compressing your spine.
For setup and form, see the RitFit AT03 belt squat attachment guide.
How do you adjust the LAM2 for better feel and targeting?
Change one variable at a time: pivot height, body position, or range of motion. A lower pivot makes presses feel more forward and up, while a higher pivot shortens the range.
- Pivot height: Too low can make presses feel like pushing forward and up, while too high can reduce comfort and shorten range. Pick a pivot that lets you press or pull through your strongest path without joint strain.
- Body position: Step closer to increase tension early, or step back to increase tension later. Face toward or away from the machine to change the resistance profile for curls and extensions.
- Range of motion: Stop where you keep control and alignment. A longer range is not better if it forces poor joint positions.
What is a good 2-day LAM2 routine?
Use a simple 2-day split alongside your normal M2 training, for example Monday and Thursday. Add load only when every set stays clean at the top end of your rep range.
Day A (Push + Legs)
- Viking Press: 4 sets of 6-10 reps
- Lever Arm Chest Press: 3-4 sets of 8-12 reps
- Belt Squat: 4 sets of 8-15 reps
- Optional finisher: Tricep Extension, 2-3 sets of 10-15 reps
Day B (Pull + Arms)
- Chest-Supported Row: 4 sets of 6-12 reps
- Lever Arm Row Variation: 3 sets of 8-12 reps
- Bicep Curl: 3 sets of 10-15 reps
- Optional finisher: Rear delt or face-pull style movement, 2-3 sets of 12-20 reps
What is the progression rule?
Pick a rep range, for example 8-12. When you hit the top end on every set with clean form, add 2.5-5 lb per side next session.
If form breaks, keep the load and build reps first. For an 8-week push, use weeks 1-2 to learn setup two reps short of failure, weeks 3-5 to add load weekly one rep short, weeks 6-7 to take only the final set near failure, and week 8 to deload with 30-40 percent less volume.
FAQs About the RitFit LAM2 Lever Arm Attachment
What is the RitFit LAM2, and what does it add to the M2
The RitFit LAM2 turns the RitFit M2 Smith Machine into an iso-lateral "leverage gym" for more machine-like training at home. It adds independent lever arms so you can press, row, curl, and extend with a guided arc, stable setup, and easier muscle targeting than free weights alone.
Which machines is the RitFit LAM2 compatible with
The RitFit LAM2 is designed to mount on the uprights of the RitFit M2 Smith Machine system. If you're using a different rack or a non-M2 frame, fit and pivot alignment can vary, so the LAM2 is best treated as an M2-specific upgrade rather than a universal lever arm set.
How much weight can the RitFit LAM2 handle
The RitFit LAM2 is rated for up to 150 lbs per arm, 300 lbs total. Because lever arms change the resistance feel through leverage and an arcing path, this range is plenty for demanding hypertrophy work on presses, rows, and arm-focused movements.
Why choose the RitFit LAM2 over a "barbell in a corner" landmine setup
A landmine uses a fixed pivot on the floor, so every rep follows a long sweeping arc that's great for athletic patterns but less efficient for clean isolation. The RitFit LAM2 gives you a variable fulcrum by letting you set pivot height on the M2 uprights, so the force line can better match the exercise you're doing.
How do I adjust the RitFit LAM2 for better feel and better muscle targeting
Adjust one variable at a time: pivot height, body position, or range of motion. A lower pivot often makes presses feel more "forward and up," while a higher pivot can shorten the range, and stepping closer increases early tension while stepping back increases late tension; facing toward or away can also change the resistance profile for curls and extensions.
Can you do a Viking press with the LAM2 lever arms?
Yes. Attach a handle to each arm, set the pivot around shoulder height, and press forward and up through a controlled arc. The guided path lets you drive explosively through the deltoids while keeping the load steady, which is harder to do with a free dumbbell press.
What is the difference between lever arms and jammer arms?
Both add independent arms to a rack, but a lever arm like the LAM2 travels on a fixed arc tied to the machine. Jammer arms are plate-loaded and move with a freer rotational path, so for clean isolation work the guided arc of a lever arm is usually easier to control.
Does the LAM2 work with the M1 Pro?
No. The LAM2 is built for the M2 Smith Machine uprights, so it does not fit other frames. If you own the M1 Pro, RitFit sells the LAM1 adjustable lever arm attachment, which is designed to match that rack's uprights and hole spacing.
Conclusion
The RitFit M2 is the heart of your home gym, and the LAM2 is the upgrade that turns it into a true bodybuilding station. Independent arms fix imbalances, a variable pivot matches the force line to each lift, and a guided arc keeps tension where a barbell loses it.
Start with the 2-day routine, adjust one variable at a time, and add load only when form stays clean. Check the RitFit discount guide before you buy, then build the leverage gym your space allows.
