First off, I want to let you know that eating is the primary mover along with progressive overload to get stronger and bigger. Honestly, past the beginner stage your gains will be minuscule or even nonexistent without a calorie surplus. You'll be spinning your wheels. If you're tight for money, or have a small appetite (this will change overtime) stick to high calorie foods that are cheap. Whole milk, peanut butter, pasta, etc. Eat about 0.8 grams per pound of bodyweight in protein and the rest being lots of carbs and healthy fats.
For training, master the heavy barbell lifts. Squat, deadlift, bench, overhead press, barbell row along with dips and chin-ups. Something like SL 5x5 or Starting Strength with added in chin-ups and dips is great for a beginner.
You could use a day or 2 to do some moderate GPP work such as sled pulling, tire flipping, etc just don't go too crazy to hinder recovery.
Most of all - focus on eating over your maintenance calories and moving more weight with solid form (after you perfect it) week after week.
