Booty King brings your program to your phone. Twelve weeks of training, a video for every exercise, and Booty King coaching you through each one. FOUR COMPLETE PROGRAMS Train in a full gym or at home with dumbbells and bands. Each program runs twelve weeks, broken into three months, with five sessions a week and rest days built in where they belong. • The New & Improved Gym Program • The New & Improved Home Program • Gym Program Vol. 1 • Home Program Vol. 1 A VIDEO FOR EVERY MOVEMENT Every exercise has a demonstration filmed by Booty King, with written coaching notes explaining what to feel, what to avoid, and how to set up. No guessing from a photograph. Hip thrusts, Romanian deadlifts, Bulgarian split squats, cable kickbacks and everything else, shown properly. KNOW EXACTLY WHAT TO DO TODAY Open the app and today's session is there — the movements, the sets, the reps, and the rest between them. Mark the day complete and your week fills in. NUTRITION THAT FITS YOUR NUMBERS Enter your stats and the app calculates your calories and macros using the Mifflin-St Jeor formula, adjusted for your goal and your diet — regular, keto, vegetarian or vegan. Then it builds a meal plan around those numbers, with every protein, carb and snack swappable until it suits you. Log what you eat, track your water, and watch the day's ring fill. TRACK WHAT CHANGES Body weight check-ins build a trend chart with your goal marked. Progress photos stay on your phone, never uploaded anywhere, so you can compare month one to month three. IN ENGLISH AND SPANISH The whole app — every exercise name, every coaching note, every meal — is written in both English and Mexican Spanish. Weights show in pounds or kilograms, height in feet or centimetres, and it remembers which you prefer. BEFORE YOU START Short talks from Booty King explaining how the program works: consistency, progressive overload, and why rest is part of the plan. GETTING STARTED New here?
