Thanks!

I compete in powerlifting, so the programs I've done--since starting to lift seriously/intentionally--are focused around that, especially recently. A quick summary (let me know if you have questions or want more details!):

• My own linear progression program that employed a split and emphasized heavy compounds
• Smolov (2 cycles)
• Sheiko/Cube Kingpin (both were only done for a few weeks)
• GZCL Method (current)

Of all of those, I saw the most squat gains by far from Smolov. The hype is well-deserved. Just started GZCL and I can tell that it's approximately as good, just more sustainable, i.e., not a competition peaking program.

Some advice that you probably already know, but just in case: record your squat to know exactly what your form looks like to pinpoint weaknesses/sticking points and to make sure you're hitting depth, weightlifting shoes do help, logging/journaling your workouts is huge (probably one of the most obviously "rational" things to do in weightlifting), and of course, get enough food and sleep.
