What does each weight plate weigh in standard gym equipment?
At the gym, some of the equipment doesn't have the weight listed on the individual weight plates, just numbers. For example, the "Hoist Fitness Systems CL2403 seated leg press" just has numbers for each weight plate, from 1 - 21. Here is a diagram of the actual CL2403 weight stack:
How much weight am I actually lifting when I set the pulley to lift different numbers of weight plates?
How much does each small round "add on weight" weigh (that I can slide over onto the stack when the weights are at rest)? See at the top right of the weight stack:
Will these answers be consistent across all weight lifting equipment, or does it change from manufacturer to manufacturer?
I have searched online and found lots of pictures of equipment, and lots of equipment for sale, but haven't been able to find anything at all on the weight bars and their specifications, let alone anything definitive.
For what it's worth, I primarily use free weights rather than isolation machines. I simply had some upper body muscle soreness the other day and could not trust myself to use anything but lower-body machines that day. I have only a couple of months of consistent gym use under my belt.
Last, you might ask why I want to know? Because I am entering my exercises in a spreadsheet and charting them. I have lost 8 pounds already, without really dieting (besides working to avoid soda and frivolous sweets). Seeing my strength and workouts improve on the chart is motivating. I'd like to enter reasonable values when I do end up using some of the machines.
I found the owners manual. Check out page 36:
The [below] chart shows the actual weight you are lifting when the ratios are applied. To find the actual weight you are lifting you would come down from the ratio being used and across from the number of the weight plate you have pinned.
The top plate weighs just under 41 pounds, and all the other plates weigh 20 pounds, but you have to add 15% due to the mechanical disadvantage inherent in the machine. So effectively, the top plate is 47 pounds and all the others are 23 pounds.
From my experience, most add on plates tend to be quarter steps to the next. For example: Plate 1 (~47lbs) and Plate 2 (~70 lbs) are 23 lbs apart. This means that Add On 1 should take you to roughly 53 lbs, Add On 2 should take you to roughly 59 lbs, Add On 3 should take you to roughly 64 lbs, and then you move up to the next plate (Plate 2 at 70lbs). This of course is based on no solid facts, just deductive reasoning based on prior experiences.
Also some standard weight bars because that is what your title asked for:
- French bar (the zig-zag looking one): approximately 18 lbs
- Olympic bar: approximately 44 lbs
Thank you very much! None of my searches turned up Hoist Fitness's own web site. Also, I probably ought to have looked for it. I could not find the weight of the "add on weights" (part #35 on page 15 and 16). Any thoughts?
I don't see anything in there @ErikE. From my experience, most add on plates tend to be quarter steps to the next. For example: Plate 1 (~47lbs) and Plate 2 (~70 lbs) are 23 lbs apart. This means that Add On 1 should take you to (roughly) 55 lbs, Add On 2 should take you to (again roughly) 63 lbs, and then you move up to the next plate (Plate 2 at 70lbs). This of course is based on no solid facts, just deductive reasoning based on prior experiences.
Wouldn't that be one-third steps? Quarter steps would be 5.75 pounds, thus stopping at roughly 53, 59, 64, then the next plate at 70. Also, the "weight bars" I was talking about are rather the "weight plates"--I didn't know the right term. So feel free to remove the info about French and Olympic weight bars.
