Here’s what I did ramping up to 405x3 front squats:
Barx5
135x5
225x4
315x3
365x1
405x3
Ramping up to 435x1 was almost the same, with one differenc:
Barx5
135x5
225x4
315x3
385x1
435x1
At 80-90%, I definitely say only 1 working set, with occasional exceptions. With 70-80%, 2 working sets is acceptable if you desire, but even then…if you’re truly going balls to the wall on that 1st set, you should only get half the reps, or less, on the 2nd set, assuming the same weight. And if you’re using less weight, what’s the point? Why would a second lighter set be beneficial? Get where I’m coming from?
Along the lines of keeping working set reps under 6 reps, that’s too much of a blanket statement, but has its uses. With big compound lifts, I usually follow that, with exceptions on occasion. Generally speaking, the less muscles involved in an exercise, the higher reps I will do. But this is best done once you have a good mind-muscle connection with a given muscle group, and have made large size/strength gains with that group. It’s hard to efficiently perform low, heavy reps, targeting the intended muscles, when your mind can’t recruit them very well.
Most common exception to the 6 rep rule is high rep squat variations, because of the legs naturally having such a large percentage of slow-twitch muscle fibers…therefore, there’s lots of hypertrophy to be had by keeping your legs well rounded. I’ve back squatted 525x1, 495x3, 315x21, 135x100, front squatted 435x1, 405x3, 315x12…you get the picture. I don’t limit my leg training to any one rep range, though it is MOSTLY below 10 reps. I happen to think it’s worked pretty well so far…to each his own.
Wow, that turned out longer than I’d expected.
