Gaining weight, made simple.
UBulk helps skinny guys gain weight and build muscle with personal calorie targets, a workout plan and progress tracking in one app.
Your first workout, another fresh start or a bulk you've already begun. You don't need a perfect routine to get going. UBulk gives you a clear starting point and the tools to keep showing up.
Know how much to eat
Get daily calorie and macro targets based on your body and weight gain goal. See what you've eaten and what's left, including protein, carbs and fat. Stop guessing whether you're eating enough to gain weight.
Spend less time logging food
Snap a meal photo for AI calorie and macro estimates, scan a barcode or nutrition label, search for foods or add your own. Adjust portions when needed. Save your usual foods and meals so your everyday shake doesn't become another daily chore.
Know what to do in the gym
Start with a workout plan matched to your experience, training days and setup. Follow animated exercise demos and log sets, reps and weights as you train. Organize your workout week and see the sessions you've completed. Gym, home gym or bodyweight training.
Get help with your next step
Ask the AI coach about your bulk. It uses your profile, goals and today's food log to make its advice relevant to you. Need a high-calorie shake or a different exercise? Get food ideas with ingredient amounts and macros, or review a workout draft and save the changes you want directly in UBulk.
See how far you've come
Record your starting weight and photos, then follow your weight trend and progress gallery. Keep track of streaks and milestones. Create an AI goal image from your starting photo to picture what you're working toward.
