How do I know if I "lift heavy" enough? Is struggling

Depends somewhat on the program, but generally speaking if your last rep of the last set of whatever lift you're doing is anywhere between "that was tough but I probably have 1 or maybe 2 reps left in me" to "that was the last possible rep I could have completed in good form," then you're probably lifting heavy enough.

Most strength programs are closer to the "last possible rep you could have done is the last scheduled rep for that lift" end of things and most bodybuilding (which is ghey af) programs are closer to the "I have another 1 or 2 reps in me for that lift" end of things, because that gives you more energy for more volume of pump and fluff lifts after the main lifts are done. So make your 3x5 and 5x5 stuff really tough at the end by selecting aggressive weights and make your 4-6x6-8 and your 2-3x10-12 stuff leave one or two in the tank by being conservative, and you've got the right path.

Wow thanks so much for the elaborate answer

You should be hitting muscle failure within 8-10 reps. If you're not you aren't lifting heavy enough.

5-6 for compounds.
