Do you really want to stroll 10,000 steps a day? And 17 different health ‘guidelines’, tackled by the specialists | Health

You’ll be able to’t use train to focus on particular areas (so sit-ups received’t provide you with a flat abdomen)

TRUE “Sit-ups will strengthen your core, however they received’t eliminate stomach fats,” says Daniel Lieberman, a Harvard College paleoanthropologist and the creator of Exercised: the Science of Bodily Exercise, Relaxation and Well being. “The excellent news is that we advanced to hold stomach fats as a short-term vitality provide, so while you begin shedding pounds by train, that’s the primary fats that’s going to get burned.”

Based on Nick Finney, a private coach whose purchasers embody Jennifer Lopez and Robbie Williams: “With a purpose to drop pounds, you want a chronic energy deficit, which you get by consuming much less and exercising extra. You’ll lose extra stomach fats doing compound workouts – deadlifts or squats – somewhat than focused workouts like sit-ups, as a result of they burn far more energy.”

Sore muscle tissue are the signal of a profitable exercise

FALSE “You’ll be able to have an amazing exercise with none soreness,” says Finney. “Delayed onset muscle soreness (Doms) is often only a signal of shock – so individuals usually discover they’re sore after their first few journeys to the fitness center, or after attempting a very totally different exercise, or a for much longer one. There are some muscle tissue, like biceps, which is able to hardly get sore – however that doesn’t imply that working them out hasn’t been profitable.”

You need to all the time stretch earlier than and after train

FALSE “Hundred of research have checked out whether or not stretching reduces the chance of damage throughout train,” says Alex Hutchinson, creator of Which Comes First, Cardio or Weights? Health Myths, Coaching Truths, and Different Shocking Discoveries from the Science of Train. “The general conclusion is that if there’s an impact, it’s too small to measure persistently. Individuals usually conflate stretching with warming up. Beginning any bout of train with some mild motion – it may be so simple as a light-weight jog – will carry your physique temperature up and make your muscle tissue extra supple. However that warm-up doesn’t want to incorporate stretching.”

You shouldn’t work out with a nasty again

FALSE “Historically, the recommendation was to keep away from sure workouts (as an illustration, deadlifts or barbell rows) in the event you had a nasty again, however theories have modified,” says Finney. “Clearly in the event you slipped a disc yesterday, you’ll wish to recuperate and rehabilitate it, however after that preliminary restoration interval, quite a lot of exercises will strengthen the again. In case you aren’t injured however have an on a regular basis dangerous again, motion is medication – it is best to 100% be figuring out. In case you by no means train the again muscle tissue, they’ll grow to be weak, which is able to depart you extra weak to damage.”

You need to purpose to stroll 10,000 steps a day

TRUE “The primary firm that produced pedometers got here up with the ten,000-step benchmark with none knowledge, as that was thought of an auspicious quantity,” says Lieberman. “Since then, loads of research have proven that steps a day is an inexpensive manner of measuring bodily exercise. As you enhance your step depend, you reap elevated advantages, but it surely tails off between about 8,000 and 10,000.”

Hutchinson agrees: “There’s nothing magic about 10,000 steps a day, however it’s fairly good recommendation. Basically, one of the best goal might be ‘a bit of extra’ than what you’re at present doing.’’

Muscle mass will flip to fats in the event you cease figuring out

FALSE “They’re two utterly totally different tissues – muscle doesn’t flip to fats and fats doesn’t flip to muscle,” says Sarah Lindsay (@roarfitnessgirl), a three-time pace skate Olympian and proprietor of Roar Health. “In case you cease exercising and eat extra energy, you’ll achieve fats. In case you cease stimulating your muscle tissue, you’ll lose muscle mass.”

Finney provides: “The confusion comes when people who find themselves significantly energetic and used to consuming lots cease coaching or grow to be injured. In the event that they keep on consuming the identical quantity and cease resistance coaching, their muscle tissue will lower and their fats will enhance – however one received’t flip into the opposite.”

Operating is dangerous to your knees

FALSE “If knees had been just like the shock absorbers in your automotive, it might make sense to keep away from carrying them out by overuse,” says Hutchinson. “However knees are a dwelling a part of your physique that reply and adapt to common use. Underusing them is dangerous for the cartilage. So when researchers comply with comparable teams of runners and non-runners over many many years, they discover that the runners are not any extra prone to develop knee issues than the non-runners. That doesn’t imply no runner will ever develop knee issues, but it surely does imply that operating isn’t worsening your odds.”

Lifting weights will make you cumbersome

FALSE “Gaining muscle is admittedly onerous,” says Finney. “On prime of lifting more and more heavy weights, it’s important to be in a calorie surplus (consuming extra energy than you might be burning). It isn’t going to occur accidentally. Some individuals keep away from weightlifting as a result of they’re cautious of gaining an excessive amount of bulk, however if you’re attempting to drop pounds, lifting weights whereas in a calorie deficit is an efficient method to do it (and can be certain that you burn fats somewhat than muscle). Plus, the stronger you might be, the heavier you raise, so the extra energy you burn.”

The extra you train, the higher

FALSE “Restoration and relaxation are actually essential,” says Lindsay. “In case you do one class within the morning and one other at lunchtime, you in all probability received’t practice very properly within the second session. Coaching increasingly will simply imply that you just’re actually drained and unable to create any depth.”

Finney suggests: “A superb benchmark to see outcomes is three exercises per week, with a relaxation day between every.”

Yoga provides you a flat bum

FALSE “Yoga received’t construct your glutes,” says Finney. “It’s troublesome to stimulate the constructing of muscle with physique weight alone – you want progressive overload, which implies lifting extra this week than the week earlier than. However doing yoga received’t lower your glutes both, so there’s no motive it ought to provide you with a flat bum.”

Evening exercise will stop you getting to sleep

TRUE and FALSE “Exercise is a stimulus, which elevates level of cortisol – an arousal hormone which is the enemy of sleep,” says Lieberman. “For most people, exercising right before you go to sleep is not going to work.” According to Finney, “Everyone is different – exercising before bedtime will stop some people from getting to sleep, but others use it to tire themselves out. You have to find what works for you and your routine.”

You should consume protein within half an hour of a workout

FALSE “The theory goes that you have an anabolic window in which to absorb protein after a workout,” says Finney. “But really, your total day consumption is the most important thing. If you want to build muscle, you should be aiming to eat 2g of protein for every kilogram that you weigh.”

Lindsay adds: “This is more applicable for carbohydrates. Your ability to store carbohydrates in the muscles as glycogen – a glucose which can be used as energy later – peaks after training, so that’s a good time to eat carbs. You do also need to consume protein, but you won’t be able to digest chicken immediately after a workout because your blood isn’t in your stomach – it has been diverted to your lungs and muscles. Straight after a workout is a good time for liquid nutrition, like protein shakes.”


“Your metabolism does decrease,” says Lindsay, “but not until you are about 65 or 70. Really what reduces your metabolism is lack of muscle – and muscle mass does reduce with age for lots of different reasons. This is why I encourage people to hold on to every pound of muscle they can – it will keep your metabolism up and makes sure that you remain strong as you age.”

You should switch routines to avoid a plateau

FALSE “People tend to switch their routine too much, perhaps because they get bored,” says Finney. “But if you want to improve at anything, you have to practise. For instance, a pull-up is brilliant at building your back and biceps, and burns a lot of calories – so if you want to do those things, it’s better to get great at pull-ups than to constantly try different exercises and never get proficient. It takes time and practice to cultivate good technique in the gym, so you’re better off focusing on the fundamentals than switching every week. A good fitness regime includes resistance training, cardio and mobility work, but switching routines too often won’t allow you to get better at the fundamentals of any of them.”

Sex is good exercise

TRUE and FALSE According to Lindsay: “If you’re trying to do cardio and elevate your heart rate, I don’t care how you do it (although the heart rate monitor might be a bit of a mood killer). It’s all good – whether you want to dance, or shag, or cycle, it doesn’t really matter.”

However, Hutchinson suggests managing expectations. “Research suggests that ‘active, vigorous’ sex burns 2.8 Mets [metabolic equivalent of task], that means you’re burning 2.8 occasions extra vitality than you’ll simply mendacity on the couch,” he says. “For comparability, enjoying a trombone takes 3.5 Mets. Operating at 10-minute-mile tempo burns about 10 Mets. It’s higher than nothing, however you’d should rack up an terrible lot of minutes in mattress to maneuver the needle as train.”

You shouldn’t work out while you’re sick

TRUE “In case you’re sick, your immune system is busy attempting to combat the sickness,” says Finney. “Understanding additionally compromises the immune system, so doing each without delay dangers making you extra sick or prolonging the sickness. It’s higher to take a few days off train than to place your immune system underneath pointless pressure.”

Hiit is essentially the most environment friendly method to train

TRUE and FALSE “A number of individuals do high-intensity interval coaching as a fast method to burn fats,” says Lindsay. “However by definition, Hiit is excessive depth – so your coronary heart fee can be too excessive to burn fats [your fat-burning heart rate is at about 70% of your maximum heart rate]. One other drawback is that inexperienced individuals aren’t sturdy or highly effective sufficient to create quite a lot of depth, so they only find yourself doing a really quick exercise.”

Nevertheless, “Hiit is an efficient method to burn quite a lot of energy in a brief period of time,” in keeping with Finney. “Ideally you’d even be lifting weights, which builds muscle, so rising your metabolism whereas at relaxation [because muscle burns three times as many calories as fat when at rest].”

Train is extra essential as you age

TRUE “Train stresses the physique, which prompts restore and upkeep mechanisms, which in flip wipe up harm and maintain us wholesome,” says Lieberman. “It produces antioxidants, which restore DNA harm; it reduces irritation, which is the reason for most illnesses; it produces brain-derived neurotrophic issue, which helps stop Alzheimer’s. Research after research reveals that train slows senescence, the deterioration related to age – so train turns into extra, not much less, essential as you become older.”
