Question Smith Machine real numbers

When doing bench on a Smith bench, whats the conversion for actual weight you are pushing? I've heard between 10-20% less than.

Well most times the bar on the smith rack weighs 5-10 lbs at most, so I guess if you're lifting 135 on a bench, you're probably not lifting much more than 95 on the smith machine...

And because no stabilizer muscles are used it makes it that much easier.
Why using a smith machine for bench? No spotter? You would be better off on a normal flat bench managing 6 to 10 reps rather than a smith machine IMO.

This isn't like drivetrain loss, LOL.

Different manufacturers have different numbers and some use counter weights and some dont. You can weigh the bar by getting a stand and putting scales on it and weighing it. Then just add how much you add to the bar to get your total.

Smith machines can be good for getting over sticking points with high weight. I use one for squats since I had my ACL reconstructed.

Just don't depend on them for everything and you'll be ok. Dumbells are great.

I would never do bench press on a smith machine, not with any real amount of weight anyway, the ideal form has the bar describing an arc. You really can't do that on a machine that moves in one dimension. You'll either have your form incorrect at the top or the bottom of the movement or both.

Yep, bench press is not a straight upward press, moreso an arch.
Stick to dumbbells, or lastly a straight bar.
Only time I use smith machine for any sort of benching, I am doing close grip...hitting my tri's.

I like the hammer strength machines for decline an incline. I prefer the bar or dumbells when working form and higher reps, but I like the added weight I can push on the hammer strength without having to worry as much about form or injury when strenght is the goal.

As for how it comares to the bench, I've never really put any thought into it. I just do the weight that I need to hit the intended rep range, whatever that may be.

Oh I agree, Hammer strength is great, love those things. I can't get used to the incline one though, it puts a lot of pressure on my shoulders so i just do incline dumbells.

The loss depends heavily on the machine. Also keep in mind that most smiths are angled, and it's important to lift in the proper direction for the muscles you're targeting.

Thanks for the replies. Unfortunately at my apt thats the closest thing I have to bench. I still do other excercises with dumbells and other machines as well as dips, etc... I wish they had a real bench there, but they dont so I have to make due. I have gained strength and weight a lot since Ive started my plan, but I know its not the same on these machines.

There are some that are angled. I prefer those for bench.

Even the angled ones suck.
I wouldn't recommend them to anyone for bench, plain and simple.

Unless that is all they had to work with I hope...

It's not a matter of what machine to use in his case, it's a matter of knowing more about the only equipment he has to work with.

You really shouldnt be able to do that much more on a smith machine. Most poeple just dont subtract the 30-40lbs that bar doesnt weigh by using one.

I sometimes do incline smith but im not a big fan of them either.
