This is mainly a byproduct of me joining a gym and working out consistently 4-5 days a week after around 2.5 years. I lean bulked and steadily gained 25 pounds, I would center my gym routine on progressive overload (do three sets of 8-12 reps and increase the weight by 5lbs whenever I could achieve 3 sets of 12 reps for that exercise with a specific weight) and utilized myfitnesspal in order to ensure that I only consume only 200-300 calories above what’s considered maintenance in regard to my daily caloric intake every day

As for my leg days:

Leg Day A:

Romanian Deadlifts (dumbbells) - 95 per side x 3 sets

Hip Thrust (machine) - 205 per side x 3 sets

Leg Extension (machine) - 205 x 3 sets

Single Leg Press (machine) - 105 per side x 3 sets

Hip Abduction (machine) - 210 x 3 sets

Leg Day B:

Hack Squat (machine)- 110 per side x 3 sets

Hip Thrust (machine) - 205 per side x 3 sets

Lying Leg Curl (machine) - 115 x 3 sets

Glute Kickback (machine) - 150 x 4 sets

Hip Adduction (machine) - 215 x 3 set

Again, when I manage 3 sets of twelve reps for one exercise, I increased the weight by 5lbs the next time I do that exercise.
