The "six pack" is the rectus abdominis, the long muscle down the front of your stomach. Everyone has one. Whether you can see it depends on two things: how developed the muscle is, and how much fat sits over it, in the layer under the skin that the trials below measured with skinfolds and ultrasound. An ab workout trains the first. Only the rest of your week changes the second.
It's a page about how abs show, not a promise that yours will or by when. The studies below measured groups of people; how your body stores and loses fat isn't something a page can see.
1. Train your abs like any other muscle
Ab exercises do what training does: they make the muscle better at its job. In a 2011 trial of 24 sedentary adults, the group that did seven ab exercises five days a week for six weeks did more curl-ups afterward than a group that didn't train, 47 against 32 on average.1 In a 2023 trial in 16 overweight men, the group that added crunches and torso rotations to its training raised its one-rep max on both by more than a running-only group did.2 Treat them like any other muscle: a few hard sets, and a little more over time. Heavy squats give the front abs about a plank's worth of work at most in the studies that measured it,3,4 so a short core block after your main lifts covers the rest: the core workout. Single moves: the cable crunch, the reverse crunch, the ab wheel and the plank.
2. Lower your body fat with the calorie side
Fat comes off the whole body when you take in less energy than you use. A 2012 consensus statement on energy balance puts the principle plainly: body weight change is associated with an imbalance between the energy in the food you eat and the energy your body spends.5 In practice that means estimating your maintenance calories, eating a little under it and adjusting from what the trend does. How to find your numbers: calories and protein. The whole-body method, step by step: how to lose body fat.
3. Don't count on ab exercises to take the fat off your stomach
This is the part most ab programs skip. In the 2011 trial above, six weeks of ab exercises had no significant effect on body fat percentage, abdominal fat, waist size or the skinfolds over the stomach.1 In a 2015 trial, 40 overweight and obese women were put on a diet, half of them with 12 weeks of ab resistance training added; both groups lost abdominal fat under the skin, and the ab training made no significant difference.6 One energy-matched trial found more: in the 2023 study of 16 overweight men, swapping part of a running session for ab and torso exercise at the same energy cost took more fat off the trunk, while total fat loss was similar, and its sessions ran almost twice as long.2 What all the trials of one spot found, side by side: how to lose belly fat.
4. Keep lifting while you lose fat
A calorie deficit can take muscle as well as fat; lifting gives your body a reason to keep it. A review of weight loss and muscle found that diet-induced weight loss reduces muscle mass, and that both endurance and resistance exercise help preserve it.7 The American College of Sports Medicine's position stand puts the trade this way: resistance training doesn't add to the weight you lose, but it may increase fat-free mass and the loss of fat mass.8 So the abs are one block in a full program, not the program: how to build muscle covers the rest of the week.
5. Eat enough protein
This site's number for people who lift is 0.7 to 1 gram of protein per pound of bodyweight a day, about 1.6 to 2.2 grams per kilogram.9,10 Aim toward the higher end while you're in a deficit, because protein helps protect muscle when calories are lower.11,10 How to reach it: calories and protein.
6. Move more through the day
Daily steps and cardio add to the energy you use. They're a helper, not the main lever: a 2017 meta-analysis of 31 studies found interval and steady cardio about even for body fat, and concluded that neither produced clinically meaningful reductions in body fat over the short term.12 Walking is the easiest kind to keep: walking for fat loss. The two kinds compared: HIIT vs steady-state cardio.
7. Judge it by the trend, not the mirror on one morning
Water and salt move the scale from one day to the next, so a single weigh-in tells you little (why you can't lose fat covers that and what to check when nothing moves). Use the slower measures instead: a weekly weight average, a waist measurement at the same spot and time of day, photos in the same light, and your lifts. How to know it's working lays them out.
Common questions
How do you get a six pack fast, in a week or in a month?
There's no honest timeline, and no study above offers one. How much fat sits over your abs, and how quickly it comes off, differs from person to person, and none of the trials was built to say when anyone's abs would show. What you control is the list above, done every week, judged by the trend.
Can you get abs at home?
Yes. The ab side needs little equipment: the core workout has a home version of every exercise, and the bodyweight workout covers the rest of your body. The fat side happens in your kitchen and your daily steps, not in a gym.
How do you get a six pack as a woman?
The same two pieces. The trials above included women: 10 of the 24 people in the six-week ab trial, and all 40 in the 2015 diet trial, where adding ab training made no significant difference to abdominal fat.1,6 Training for the rest of your body: strength training for women.
Can a 5-minute ab workout give you abs?
A short ab routine trains the muscle, and that's worth doing. It doesn't uncover it: in the six-week trial, ab exercises five days a week improved curl-ups and left abdominal fat unchanged.1
Do squats and deadlifts work your abs?
Some. In the studies that measured it, heavy squats worked the muscles along the spine harder than a plank and the front abs about as hard as a plank at most.3,4 The studies, and the block to add: do squats and deadlifts already train your core?
If you'd rather have someone read the trend
The list is short; holding a small deficit, a lifting program and enough protein week after week, and knowing what to change when the trend stalls, is the hard part. Coaching is the version where your workouts live in Trainerize, built around the days you actually have, and someone reads your weigh-ins, photos and logged workouts every week and adjusts the plan. Fat loss coaching explains how that works, and apply is the first step. Otherwise: add the core block to the end of your next two sessions.
