I just saw this on
Jason Ferruggia's site. Turns out it is a promotion for his latest book, but I found that I agreed with his 5 points. They are:
1) The importance of properly periodized strength work in
your programs.
2) Why submaximal training delivers maximal gains at a much
faster rate then always going too heavy or too close to
failure.
3) The mistakes most people make with single leg training
and why you might be more doing more damage than good if
you're falling victim to this trap. (Hint: if you're
stretching your quads from the knee instead of the hip
you're asking for problems)
4) Why deloading is critically important to your long term
progress and ability to remain injury free. This has to be
done correctly if you plan on training for many years into
the future.
5) The proper balance between pulling and pushing exercises
for strong, healthy shoulders.
I'd just say that point 3 seems like a detail, not an overriding principle. I'm not sure what he's saying about that. I'll read his site further.
