Of course, no one was born pressing 500 pounds or squatting 700 pounds – it takes time to build this kind of strength. Assuming your form/technique is in place, you'll want to incorporate some low reps and heavy weights into your program. For example, do 10 sets of squats for 3-4 reps each, or 8 sets of 5. In other words, in order to build strength, keep your weight heavy and use low reps for a high number of sets. Squatting your bodyweight is a bare-minimum requirement for a beginner (or twice your bodyweight for an intermediate-level lifter).
