I can max around 250(1 rep)... 275 with a little help. Dumbbells require a lot more control and muscles used are a lot more localized. I've never maxed out with dumbbells but im sure i can get 85's up a couple times. I was doing 75s yesterday for maybe 2-3 reps with no spot. It's definately a lot easier to lift with a spotter because you dont have to worry about dropping the weight on yourself.

look here.

or google for "1RM calculator" (one rep max)

That calculator thing is pretty cool. It seems to be pretty accurate if you put in your reps/weight aroun 10 or under, for example 205 8 times maxing out at 254, but I can do probably 20 reps at 175 pounds but I cannot max 280 pounds. However all in all this gives you a pretty good idea, thanks for the link.

deeko is right, everyone is different. i am opposite of deeko. i could barbell 155lbs bench 3 of 10 while if i do dumbells a pair of 75's i do 10, 10, 6-7. you would think i could do more on barbell looking at me doing dumbbells bench but not true for me. i don't do barbells much since i rarely have a partner and its safer if you can't get that last rep doing dumbbells.

Yeah I can rep on 275 (6 times) and it says my max is 324, cool. :)

W/out a doubt dumbbells are harder. You should always have a spot with both, barbell and dumbbells for bodybuilding. Anything less and you're cheating yourself out of maximizing muscle growth, and jeopardizing your safety.

What a completely worthless reply. Every non-idiot knows that there is no "one size fits all" formula that applies to everyone. If you don't know this...

most of the 1RM calculators give good estimates for about 7 reps or less (and fail wildly for more than 10 reps).

some are specialized for different lifts, but that one's a good overall predictor.

I agree with Spamela here, is there some sort of requirements for posting a reply now? IF that's the case we'd better discontinue with 90% of the posts here that consist of but not limited to a smiley face, the phrase "pics", or "link". What's up Marshallj, I sided with you most of the time in the "war and middle east" forum but i've seen you either picking a lot of fights or partaking in a lot even if you didn't initiate it here. Ya, I'm a huge lurker.

If someone wants to make a point, make it. But just making a smartass comment or a wisecrack is not contributing to the discussion whatsoever.

That 1RM calculator can only give estimates based on the "average" person with "average" endurance. Someone who is very very lean (like I used to be) may be able to do more reps of a certain weight than the average person, yet do less MAX weight (1RM) than the average person.

If a person's weightlifting routine is all about high reps/low weight, they'll probably be able to do a lot of reps, but their all out strength for 1 rep will be lower. On the other hand, a power lifter whose routine is very high weight, very low reps will be able to do a lot of weight on 1 rep, but their muscle will probably not be lean enough to do many reps of a lower weight.

Not everyone is "average", some people optimize for endurance, others optimize for all out power, explosive strength. Such a formula doesn't take into account what kind of muscle you have.

the formulas used in the 1RM calculators are based on statistical sampling, so they're going to be fairly accurate for the vast majority of lifters with average genetics for a "small" number of reps.

IMHO, any 1RM calculator that asks a bunch of "do you have fast or slow twitch muscles?"-type questions isn't going to be used and doesn't provide much extra value, anyway.
