If you’re new to the gym, one of the first questions you might ask is, how much is each weight on a machine? It’s a smart question, as knowing the weight helps you track your progress and train safely. This guide will explain how to find that information on any machine and use it effectively.
You’ll learn to identify weight stacks, plates, and pin settings. We’ll cover different machine types and give you tips for a strong start.
How Much Is Each Weight On A Machine
Most gym machines use a weight stack. This is a tall stack of rectangular plates with a pin you insert to select your resistance. The total weight you lift is the sum of all plates from the pin upwards.
Finding the weight per plate is usually straightforward. Look for a label or sticker on the side of the stack. Each plate often has its weight marked directly on its edge.
Common Weight Increments on Stacks
Weight stacks typically increase in set amounts. Here are the most common increments you’ll see:
- 5 lbs per plate: Very common, especially on older or lighter-duty machines.
- 10 lbs per plate: Perhaps the most standard increment in commercial gyms.
- 20 lbs per plate: Common on leg press, hack squat, or other heavy leg machines.
- 5 kg per plate: Standard in gyms using the metric system (about 11 lbs).
- Variable Increments: Some stacks mix plates (e.g., 10lb and 5lb plates together).
What If the Plates Aren’t Labeled?
Sometimes labels wear off. If this happens, don’t guess. Ask a staff member—they’ll know. You can also check the user manual placard on the machine, which often lists the plate weights.
Another method is to compare with a nearby, labeled machine from the same brand. They often use the same stack design. Never assume the weight is light; always verify.
Decoding Different Types of Weight Machines
Not all machines show weight the same way. Understanding the three main types will clear up any confusion.
1. Selectorized Weight Stack Machines
This is the classic gym machine. You move a pin to choose a weight. The number on the pin usually corresponds to the plate, not the total pounds.
- Example: If each plate is 10 lbs and you put the pin in plate #6, you are lifting 60 lbs (plus the starting weight of the carriage, if any).
- Check for a “Start Weight”: Some machines have a base resistance. The placard might say “Start Weight: 20 lbs.” This means you add that to the stack weight.
2. Plate-Loaded Machines
These machines have horns or posts where you add standard Olympic plates (the big ones with a 2-inch hole) or smaller bumper plates. The weight is exactly what you load.
- Leg press, hack squat, and some chest press machines use this system.
- Remember to count both sides! Loading a 45-lb plate on each side equals 90 lbs of total resistance.
3. Friction or Hydraulic Resistance Machines
Common in some circuit gyms or rehabilitation centers, these use fluid or air pressure. They often have a dial numbered 1-10 or 1-20. These number are levels, not pounds. The placard should show the equivalent resistance for each level.
A Step-by-Step Guide to Finding Your Machine’s Weight
Follow these steps every time you approach a unfamiliar machine.
- Locate the Information Placard: Look for a diagram or instructions on the machine’s side or frame.
- Examine the Weight Stack: Check the edge of each plate for stamped or sticker numbers.
- Identify the Pin: See what number the pin is on. Note if the count starts from the top or bottom.
- Do the Math: Multiply the plate weight by the plate number. Add any starting weight.
- Test the Movement: Always try the weight with good control before committing to a set.
Why Knowing the Weight Matters for Your Progress
Tracking your weights is the single best way to see if you’re getting stronger. If you don’t know how much you lifted last week, you can’t plan to lift more this week.
It also prevents injury. Jumping to a weight that’s to heavy is a common cause of strain. Consistent, small increases are the key to long-term success. Writing down your numbers might seem simple, but it’s a powerful tool.
How to Log Your Machine Weights
Use your phone’s notes app or a dedicated notebook. For a selectorized machine, your entry should include:
- Machine Name (e.g., Seated Row)
- Plate Weight (e.g., 10 lbs/plate)
- Pin Setting (e.g., Pin #7)
- Total Weight (e.g., 70 lbs + 15 lb start = 85 lbs)
Common Mistakes and How to Avoid Them
Even experienced lifters can make errors with machine weights. Here’s what to watch for.
Mistake 1: Forgetting the Weight of the Carriage
Some machines counterbalance the weight stack, so the first plate feels light. Others have a heavy carriage. Always check the placard for “starting weight.”
Mistake 2: Misreading the Pin Number
Does pin #1 mean the top plate or the bottom? Systems vary. The placard or stack label will tell you. If it says “Weight per plate: 10 lbs” and shows a pin in #5, the total is usually 50 lbs.
Mistake 3: Assuming All Machines Are the Same
A leg press plate is often heavier than a lateral raise machine plate. Never assume the increments are identical across different machines, even in the same gym.
FAQ: Your Machine Weight Questions Answered
Q: The pin has numbers, but no weight is listed. What do I do?
A: First, look closely at the plates themselves for markings. If there are none, ask a gym employee. You can also carefully lift the top plate to feel if it’s 5, 10, or 20 lbs, but asking is safer.
Q: How much weight is on a Smith machine bar?
A: The bar on a Smith machine is often counterbalanced. It’s weight can vary from 0 lbs to 35 lbs. Your gym should have it marked. If not, treat it as a 15-25 lb bar until you can confirm.
Q: Do the assisted pull-up/dip machines show the weight I’m lifting or the help I’m getting?
A: They show the assistance. If you weigh 200 lbs and set the machine to 50 lbs, you are lifting roughly 150 lbs of your bodyweight. A lower number means less help, so it’s harder.
Q: Are cable machine weights the same as stack machines?
A: Yes, cable stations usually use a weight stack. The same rules apply. Check the plate labels to find the increment, which is often 10 or 20 lbs.
Q: What if a machine feels heavier or lighter than the number says?
A: This is normal! Leverage, pulley systems, and machine angle change the feel. A leg press weight will always feel different than a squat with the same weight. Focus on consistent progress on each individual machine, not comparing numbers between them.
Putting It All Into Practice
Now you know how to answer the question, how much is each weight on a machine. Start by learning the increments on your favorite three machines next time you workout. Write them down.
This knowledge turns random exercise into structured training. You can make clear goals, like adding one plate every two weeks. This leads to real strength gains over time. Remember, everyone started not knowing these details—asking questions is a sign your a smart lifter.
Finally, don’t let the numbers intimidate you. The right weight is the one that challenges you while allowing good form. Whether it’s pin #3 or #13, what matters is that your pushing yourself appropriately. Consistency with tracking will show you results faster than you think.
