The Five Biggest Contradictions in Fitness

Itís no secret that when people contradict themselves, it has the effect of making the flaws in their actions or statements seem glaringly obvious. But what about when WE ourselves get caught contradicting ourselves by someone else?

    what do you believe the conversion from DB to BB is?

    For me it is about 35 lbs

    Not sure what you mean.

    For me it's a lot more than that. For instance I use 85lb db's for reps, but use much more than +35lbs for reps using bb bench. Now if you're talking about both dumbells together, then 35lbs is somewhere in the ball park.

    what is mean is if I am using 2 80lb dumbells for reps (160lbs total), then what I do on barbell for that exercise is normally about 35 lbs more (195 lbs).

    There is no set 'conversion.'

    When one switches from BB to DB the muscles are shocked and aren't used to it. It's like 2 completely different exercises. It's just what the muscles are used to doing and keep in mind that different muscles are used doing BB and DB for a given exercise. So, it depends on a lot of things.

    I understand that, but I still think there would be a "general" conversion. I use both DB's and BB's for the major chest exercises (alternate).

    Well, probably the "general conversion" would be like 75% of BB with DBs.

    i do 90s for incline db, so that would be 180, but I only do 195 for incline bb, so that is only 15 lbs, and I have no idea what I do on flat db because the highest my gym has is 100s and im way past that

    Quick story about this. I used to only do DB bench press for benching; never did the BB bench press. I got up to a pair of 90's. When I finally switched over to BB bench press, I could only do about 165. I think there are slightly different pieces involved on both lifts and realistically, while the lifts work the same muscles, they can not be compared, just like a flye and a press can't be compared. On another thought, If you just look at the movement of both exercises and the muscle groups worked, then idealy, you should be able to push the same weight on either. To do this, you'd probably have to do a BB and DB press every time in the same workout (or at least alternate). Only thing really limiting the DB is the mount, dissmount and stabalizing factor since you are pushing two objects instead of one. Ultimately, I still think they are two completely different exercises and like most people have said: it doesn't matter.

    as mentioned earlier the conversion is more likely to be a percentage than a set number of lbs.

    the BIGGEST diff. between the two is that with a bb the stronger arm can compensate for the weaker arm and with dbs you get a larger ROM. because the bottom of the lift where you get the extra ROM is where you're weakest you won't be able to lift as much with the dbs even if you have perfect symm. this stands for all lifts.

    I'm with the "it doesn't matter" crowd. It's going to be different for different exercises.

    i've always wondered about this too..

    i have heard somewhere between 70-80% of your barbell bench press should be the combined weight of the 2 dumbbells in your dumbbell bench.

    the last time i barbell benched (looong time ago)
    i was pushin up 285 for 7 reps.

    i have since switched to dumbbells and i am currently using 115's x 5-6 reps

    so that's about 80.7%... probably will differ greatly among various body types and genetics, etc... longer arms vs. shorter.. height, weight.. blah blah. i would say 70-80% is a safe estimate though.

    Good to see that I'm not the only one that sticks to dumb bell presses 2 90's 8 reps x4. Tore my rotator cuff about 4 years ago doing barbell presses and was advised to stick too dumb bells less stress on the shoulders will do 225 lbs from time to time on the barbell. Don't want to go through the hell of surgery and recovery of that again and I'm not so young anymore.......

    You can severely damage your RC on a bench press if you do not keep the shoulders pulled back tightly through the entire ROM. Some people like to push the shoulders out/forward as they near the top of the lift. This puts all the load on the joint, which is not being supported by the back muscles when it's shifted forward. This is bad news for the RC.

    Yeah, a lot of people think you need to shift the shoulders forward on the lift to get that "extra flex/contraction" of the pecs. This is crap, the lift is already over at that point in time anyway. All you are doing is shifting the load onto the RCs. Also, not sure if it's clear, but what I mean by "shifting forward" is when the shoulder piece actually moves out in front of the body just slightly. You want it pulled back tightly and reenforced by all the back muscles. You'll notice the difference almost immediately if you are pushing the shoulders forward on your benches.
