Phrak's Greyskull Linear Progression Program (GSLP) is a popular beginner lifting program on Reddit and across the internet. It has an excellent balance of push and pull movements to help you develop a balanced physique.
The program is 3X a week, with 2 alternating days of whole body training. Weights increase every workout on the compound movements–squat, bench, deadlift, rows, and chin-ups–with a mix of bodybuilding isolation exercises at the end of the workouts.
Rules for GSLP:
Make sure to warm-up before entering into your working sets
Last set is for As Many Reps As Possible (AMRAP) with good form
Progress with 2.5 lbs for upper body lifts and 5 lbs for lower body lifts (automatically in the app)
If final AMRAP set hits more than 10 reps, consider doubling the weight increase
If you cannot do weighted chin-ups, use assisted pull-up machines or negative chin-ups until you can do bodyweight chin-ups, then slowly add weight
If you fail to get 5 reps in the final AMRAP set, stay at the same weight as last time. If you fail again, then deload by 10% and increase again.
The program can be run for as long as it is effetive, but at least 6 weeks is recommended
