Q: Charles, you've not commented much about Tribex or Power Drive, why? Is the reason for your reticence, because you haven't had much experience with these supplements, or is it because you're not keen on them. I'm not trying to be disrespectful, nor is it my intent to cause a big scandal. Please be open with your response. I mean, really tell it like it is.

Q: A few years ago, I read an article of yours concerning the "critical drop off" point. You stated that when a muscle reaches a 5%-7% decrease in performance (either in weight or reps), that particular exercise should be terminated. My problem is that I usually reach this point after only 1 or 2 sets! For example, I was performing incline dumbbell presses on a Swiss ball using 110 pound weights for 4 reps at a 505 tempo. After 4 minutes of rest, I could barely perform 2 reps at the same tempo. I dropped down to 100 pounds for the third set and got 3 reps; and then dropped down to 90 pounds for the fourth and got 3 reps. Each set had 4 minutes rest. The same thing happens no matter what rep tempo I use.

My question is, should I continue to perform multiple sets and just allow the weights to drop, or should I terminate the exercise after only one or two sets?

Finally, I just want to say its wonderful to have this forum in which to pose questions. Over the years, I sent several questions to MM2K for you to answer, but I always got a response from some fitness trainer at MM headquarters.

Q: You've convinced me to take tempo seriously. I even bought a metronome, but I have a question. I usually take all my sets to concentric failure. The last rep might take twenty seconds to squeeze out. However, tempo implies all reps take the same amount of time under tension. Should I consider a rep a failure if I cannot achieve it with good form fast enough? Will I still make gains if I don't push myself to grind out those slow painful final reps?

Q: In last week's "Question of Strength," you mentioned one-arm dumbbell shrugs. How do you do these, especially with a heavy weight?

Q: In response to a previous question about the powerlifter wanting to drop body fat without losing strength, what kind of dietary manipulation would you recommend?
