Best Workout App for Building Glute Width
Width comes from side glute work done properly, so pick the app that checks the reps instead of trusting a tick box.
The Butt Lift teamUpdated 2026-08-13
Short answer
Butt Lift is the strongest pick for glute width. Its V-Shape Builder program targets the side glutes and waist, and the iPhone camera counts each rep and scores it live on depth, tempo and control.
Fitbod suits loaded gym training better. Sweat suits anyone who wants trainer-authored programmes. Shape is largely genetic; training changes muscle size and strength.
The short version
- Butt Lift's V-Shape Builder programme targets the side glutes and waist, the area that drives glute width.
- The iPhone camera counts each rep and scores it live on depth, tempo and control, so shallow reps are flagged rather than counted clean.
- Fitbod is the stronger pick if you train loaded in a gym, because it selects sets, reps and weights and adapts from what you log.
- Sweat offers trainer-authored programmes with home and gym variants, but like Fitbod it expects you to self-report every set.
- Training changes muscle size and strength; hip bone structure and muscle insertions are genetic and no app changes them.

What "glute width" actually responds to
Width lives at the side of the hip. Fire hydrants, curtsy lunges and sumo squats are the honest tools here, done with real range and enough sessions.
Hip width and insertion points are genetic. Training changes muscle size and strength, not bone structure.
So the question is which app checks the side glute work is done well, not which one promises a shape.
The apps, compared honestly
Most glute apps are a video plus a tick box: you watch, you copy, you mark it done.
Butt Lift verifies each rep with the camera; the others rely on you to self-report. That matters most for width, because abduction work is the easiest thing to half-do.
- Butt Lift: three shape programs, camera counts and scores every rep
- Fitbod: strongest programming for loaded progressive overload in a gym
- Sweat: trainer-authored programmes with home and gym variants
- 30 Day Butt Challenge Pro: ready-made 30 day video plan, nothing verified
- Booty Builder: squats only, so no side glute work at all
Why Butt Lift is different
It is personalised glute training with automatic rep counting and form scoring, not a video you follow along to.
The iPhone camera counts each rep and scores it live on depth, tempo and control.
Sloppy reps score lower and get flagged with a cue; a clean rep streak drives the combo.
Pose detection runs on device, and no video is recorded, stored or uploaded. No account either.
Onboarding builds a 28 day plan from your answers: program, strength, weekly frequency, session length and focus areas. It is not one fixed plan for everyone.
Ten glute focused exercises cover the patterns that matter for width, including fire hydrant, curtsy lunge and sumo squat. It adapts from bodyweight to bands and dumbbells.
It reroutes around flagged knees, hips, lower back or wrists, with sessions from about 5 to 25 minutes. Butt Lift trains and measures; it does not promise an outcome.
Which of the three programs to pick
V-Shape Builder is the one for width, focused on the side glutes and waist.
Lift & Sculpt aims at upper glute lift instead, so pick it if you want shape higher up rather than out at the sides.
Full Curve is the balanced all round option if you want the whole thing trained evenly.
You choose in onboarding alongside strength, frequency and session length, so the plan is built around the choice rather than bolted on afterwards.
When a rival is the better buy
Training loaded in a gym? Fitbod is the stronger pick for progressive overload: it recommends sets, reps and weights and adapts from what you log.
Sweat wins on authorship and community, with programmes from named trainers and home or gym variants. Neither verifies a rep; both expect you to self-track.
Booty Builder trains squats only, so it cannot do side glute work at all. Skip it for this goal.
30 Day Butt Challenge Pro has the widest platform support, running on iPhone, iPad, Mac and Apple Vision, with HealthKit sync and habit extras.
Questions people ask
Can you cheat the rep counter?
Not easily. The camera scores each rep on depth, tempo and control, so a shallow or rushed rep scores lower and gets flagged with a cue instead of counting as a clean one.
Does Butt Lift record me?
No. Pose detection runs on device, and no video is recorded, stored or uploaded. You do not need an account either.
Will an app actually make my hips wider?
It can train the muscles at the side of the hip, which changes size and strength. Bone structure and where your muscles attach are genetic, and no app changes that.
Do I need equipment for width work?
No. Butt Lift adapts to what you have, from bodyweight through to bands and dumbbells, so fire hydrants and curtsy lunges work with nothing at all.
What if my knees or lower back play up?
Flag them in onboarding and the plan reroutes exercises around knees, hips, lower back or wrists. Sessions can be set as short as about 5 minutes.
How long are the workouts?
You choose in onboarding, roughly 5 to 25 minutes, and the 28 day plan is built around that alongside your weekly frequency.
