So who else's gains are being held back by lack of a training partner? I go to a golds gym that only has one cage (and 3 smith machines

). So I rarely have a chance to work out till failure.
For those of you with good training partners don't take them for granted.
There are some pretty big guys who train alone, safely. You have to be creative, one way I have found to really maximize this is to do this:
Using things as you mentioned, Smith Machine but also, dumbells and the new hammer strangth mahcines. If you are at Gold's I am sure they have all the above.
What you want to do is failure, safely. So, lets say you are doing bench, Dumbell bench, Hammer strangth bench, or Smith which actually works less effective than these other 2 for this excersise.
Say you are doing 3 or 4 sets of 8 to 12. On your last set, last rep you know when you are going to fail, on the rep right before that, the rep where you usually rack the weight, instead of racking, bring it down really slow and controlled, as slow as you can, all the way to the bottom, get a good strecth and drop the Dumbells/release the hammer stregnth.
See with a smith machine the bar may be to low, but, the other 2 this works great.
Plus with all other lifts you can do the same technique safely.
NOW NO EXCUSES!
Good question though and a common problem.
Also this last rep to failure downwards is also something you may find in a DC Workout.
Have a good day, and good luck!
