The only bad practice I have is lifting weights alone, and this tends to make me “baby” myself on the amount of weight I am willing to use.

Using too much weight is probably one of the biggest mistakes at the gym. For some reason, guys are particularly guilty of this when it comes to dumbbell bicep curls.

If I had a dollar for every time I watched someone cheat up a dumbbell with their shoulders and back .

Here’s great example of a guy “ego lifting” — this is supposed to be a dumbbell hammer curl. His upper arms and elbows should be in tight to his body and there should be no movement at the shoulder. Somehow, though, he manages to turn it into some Franken-exercise that’s a cross between a bicep hammer curl and an upright row. Very weird. Check it out for some entertainment:

Now, I’ll give the guy credit for chisling out a nice physique — but I don’t think it was from this particular exercise.

The bicep pose at the end is priceless.
