FLEX vs. BLOB

Myths BustedEvery fitness myth from the comic, in one place.

19 myths busted so far. Every week Flex, Blob and Dan run into a fitness myth. Here they all are, with the short version of the truth and a link to the episode.

  1. EP. 19Training

    Do you need to keep confusing your muscles?

    Myth: You have to keep shocking or “confusing” your muscles, or they stop growing.

    Reality: muscles don't get scared or confused. They grow from progressive overload: doing a little more over time, consistently. Swapping some exercises now and then is fine and keeps training fun, but changing everything all the time makes progress hard to track and can slow it down. Same plan, a bit heavier each week. And kettlebells only work if you lift them.

    Can a walking pad replace a workout?

    Myth: A walking pad melts the fat while you work. Who needs a gym?

    Reality: slow walking at a desk burns roughly 90–120 extra calories an hour compared with sitting. That's real, and moving instead of sitting all day is good for you. But one croissant cancels about an hour of it, and strolling won't build strength. Treat it as a bonus on top of your workouts, not a replacement. And maybe sit down for the big presentation.

  3. EP. 17Recovery

    Do muscles grow in the gym or while you sleep?

    Myth: Muscles grow in the gym.

    Reality: the gym only sends the signal. Repair and growth happen while you recover, and deep sleep is when the body releases most of its growth hormone. In one study, a single sleepless night cut muscle-building by 18%. Short sleep also raises hunger hormones, which is why Blob loves 2 a.m. Adults need 7 hours or more.

  4. EP. 16Training

    Do you really need 10,000 steps a day?

    Myth: 10,000 steps a day is the scientific magic number.

    Reality: it started as the name of a Japanese pedometer, the “manpo-kei” (10,000-step meter), sold after the 1964 Tokyo Olympics. A 2022 review of 15 studies found the benefit levels off around 6,000–8,000 steps for people over 60 and 8,000–10,000 for younger adults. Every walk counts. The last 600 steps at midnight, instead of sleep, don't.

  5. EP. 15Training

    Should you skip exercises that leave you sore?

    Myth: If an exercise leaves you limping, skip it. Stick to the ones that feel easy.

    Reality: lunges feel brutal because they're hard: one leg does the work while also keeping you balanced, so they find every weak spot and every left-right difference. That's exactly why they're worth doing. And there's good news, called the repeated bout effect: after the first tough session your muscles adapt, and the same workout leaves you far less sore the next time. Start small (bodyweight, shorter steps; reverse lunges are kinder to the knees), do them once or twice a week, and add a little at a time. Muscle soreness is normal. Sharp pain in a joint is not: that's a signal to stop and get it checked.

    Does lifting heavy make women bulky?

    Myth: If a woman lifts heavy, she gets bulky like a bodybuilder.

    Reality: women have roughly 10–20 times less testosterone than men, so building a lot of muscle takes years of focused training and eating for it. It's a goal some women choose, not something that happens by accident. What strength training does bring: stronger bones (one of the best defences against osteoporosis), better posture, easier everyday life and more confidence. And, apparently, the ability to re-hang a door before your first coffee. Bonus: being strong doesn't mean being reckless. Coach Ana is stronger than Dan and still waits for the key.

    Is a glass of red wine a day good for your heart?

    Myth: A glass of red wine a day is good for your heart.

    Reality: the idea came from old studies where many “non-drinkers” had quit because they were already ill, which made moderate drinkers look healthier. Better research finds no real benefit, and the WHO says no amount of alcohol is good for your health. A glass of wine has about 120 calories, slows fat burning while your liver clears the alcohol, and makes your sleep worse. The fresh must? A mug has about as much sugar as a can of cola. Drink wine for the taste, not as medicine. The healthy part of Dan's day was the harvest. Safety tip: fermenting wine fills the cellar with carbon dioxide, so air it out before you go down.

    Is homemade zacuscă “just vegetables”?

    Myth: It's just vegetables, so you can eat the whole jar.

    Reality: zacuscă is mostly peppers, eggplant and onion, which is great: fibre, vitamins, real food, made at home. But traditional recipes use a lot of sunflower oil, and one tablespoon of oil has about 120 calories. So a jar is closer to a meal than a snack. Enjoy it on bread, in normal portions, and keep the rest for winter. That's why Mama made 27 jars.

  9. EP. 11Training

    Do you need a gym to get fit, and does sweating burn fat?

    Myth: You need a gym to get fit. And sweating a lot means you're burning fat.

    Reality: long before gyms, people got strong by working: digging, carrying, lifting and walking all day. Gyms just package those movements, and the farmer's carry is literally named after it. Gardening, stairs and carrying shopping all count. Build up gradually, bend your knees and keep your back straight: Bunica has 60 years of practice. And sweat is mostly water you'll drink back. Fat loss comes from regular movement and what you eat over weeks, not from one sweaty afternoon.

    Are rest days for the weak?

    Myth: No days off. Rest is for the weak.

    Reality: training breaks the body down. It gets stronger while it recovers. Push hard for weeks without a break and you get stalled progress, niggling injuries, bad sleep, a short temper and a motivation crash. That's why many training plans include an easier “deload” week every 4 to 8 weeks: lighter weights, fewer sets, more sleep, gentle movement. Your head works the same way, and gym stress adds to work and life stress. If exhaustion, low mood or anxiety stick around even after rest, talk to a doctor or a mental health professional. That's training too.

  11. EP. 9Mindset

    Do people who stick with training just have more motivation?

    Myth: People who stick with training are just more motivated than you.

    Reality: everyone's motivation goes up and down, pros included. What keeps them going is routine: a fixed time, gear ready the night before, a small goal for bad days, and a way to track progress. Habits form by repeating the same thing in the same context. In one well-known study it took about two months on average, with big differences between people, and missing a single day didn't break the habit. Blob's snack habit works exactly the same way. Use his weapon against him.

    Will training like a pro make you look like one?

    Myth: Train like a pro and you'll look like a pro.

    Reality: pros like Seba build their workload over years, with coaches, physios, a nutrition plan and a lot of sleep. Copying their sessions as a beginner mostly gets you injured. Copy their habits instead: warm up properly, train consistently, eat real meals, sleep 7 to 9 hours, and recover like it's part of the job. Because for them, it is.

    Is gym strength useless in real life?

    Myth: Gym strength is just for show. You'll never use it in real life.

    Reality: grip, back and core strength are exactly what you use to carry shopping, lift a kid, or hold a friend's belt over a lake. Studies even link grip strength to healthier ageing. Bonus fact: body fat is less dense than water, so Blob is right. He does help you float. (Wear a life jacket anyway.)

    Does kinesio tape prevent knee injuries?

    Myth: Colourful kinesio tape protects your knees from injury.

    Reality: the evidence that tape prevents injuries is weak. Some people feel a bit less pain or more confident with it, and that's about it. What actually protects knees: strong legs, good technique and not doubling your workload overnight. To take tape off, soak it with oil or in the shower, hold the skin down, and peel slowly in the direction the hair grows.

    Does one cheat meal ruin weeks of clean eating?

    Myth: Eating clean means zero treats forever, and one slice of cake undoes weeks of work.

    Reality: progress comes from what you do most of the time, not from one slice. Strict all-or-nothing rules often backfire into a full pizza weekend. And yes, short sleep and stress really do make cravings louder. Blob didn't invent that. He just uses it.

  16. EP. 4Injuries

    Should you push through shoulder pain?

    Myth: Shoulder pain? Push through it, or let a search engine diagnose you.

    Reality: a common beginner cause is too much overhead work, too soon, with no warm-up. Pain that lasts more than a few days, gets worse when you lift your arm, or wakes you at night is a job for a physiotherapist or doctor, not for Flex, Blob or a search bar. Rehab is often boring bands and patience. Boring works.

    Does training as hard as possible every day get you fit faster?

    Myth: The harder you go every single day, the faster you get fit.

    Reality: CrossFit isn't the problem. Going from couch to maximum effort every day is. Muscles get stronger while they recover, not while they're being flattened. Scale the workout, learn the technique first, and take rest days. Your joints will send a thank-you card.

  18. EP. 2Recovery

    Is muscle soreness caused by lactic acid?

    Myth: Muscle fever is lactic acid stuck in your muscles, and the more it hurts, the better the workout.

    Reality: lactic acid clears within about an hour. The soreness (DOMS) comes from tiny damage in the muscle fibers after new or unusually hard exercise, especially the lowering part of a move. It peaks 1 to 3 days later, fades as you train regularly, and says nothing about how good the workout was. Light movement helps. (Blob hates that part.)

  19. EP. 1Nutrition

    Is a “high protein” snack automatically healthy?

    Myth: “High protein” on the front of the box means it's healthy.

    Reality: turn the box around. Protein helps muscle repair after training, but it doesn't replace the training. Extra calories still land somewhere. (Ask Blob.)
