Fitness & movement: questions answered
Workouts, soreness, steps, protein and what actually builds strength at any age.
How long until I see results from working out?
You feel results before you see them. Most people notice better energy, mood and sleep within two weeks. Strength climbs quickly in the first month, mostly because your nervous system learns the movements before the muscles themselves grow.
Is walking enough exercise?
For your heart, walking is largely enough exercise. Brisk walking that raises your breathing counts fully toward the 150 weekly minutes in the guidelines, and it lowers blood pressure, blood sugar and early death risk in study after study.
Should I do cardio or weights to lose fat?
For fat loss, neither cardio nor weights burns fat the way people hope. Food decides fat loss; exercise decides what your body looks and works like as the weight comes off. A calorie deficit does the losing.
Why am I most sore two days after exercise?
That delayed ache has a name: delayed onset muscle soreness, or DOMS. Unaccustomed effort, especially the lowering half of movements, leaves microscopic damage in the muscle. The repair process, not the workout itself, is what aches, and it peaks around 24 to 72 hours later.
How much protein do I need after a workout?
Around 20 to 30 grams of protein in the meal after a workout is plenty for most people. That is a chicken breast, three eggs, a cup of Greek yogurt, or a standard scoop of protein powder. More than that in one sitting adds little.
I am over 60 and have not exercised in years. Where do I start?
Start smaller than pride suggests and sooner than doubt allows. Ten minutes of marching in place, sit-to-stands from a sturdy chair, wall push-ups and heel raises is a real workout at any age, and it rebuilds exactly the strength daily life uses.
Should I work out every day?
Moving every day is healthy. Training hard every day is not. Muscles grow and joints adapt in the hours between sessions, so hard efforts need easier days around them.
Why am I gaining weight after starting to exercise?
Weight gain after starting exercise is almost always water, not fat. Newly trained muscles store extra glycogen, and every gram of glycogen holds water with it. Mild repair swelling adds a little more. A pound or three in the first weeks is completely normal biology.
Do I really need 10,000 steps a day?
No, you do not need 10,000 steps a day. The 10,000 figure began as a Japanese pedometer marketing campaign in the 1960s, not as science. The research done since tells a friendlier story.
Is it better to work out in the morning or evening?
The best time to work out, morning or evening, is the one you will actually repeat. Across studies, the health differences between morning and evening training are small; the difference between exercising and not exercising is enormous.
Do I need a rest day?
You need recovery, which is not quite the same as a day on the couch. Muscle is built between sessions, not during them, so hard efforts on the same muscles need about 48 hours between them.
Can exercise lower blood sugar?
Yes, exercise lowers blood sugar, and it does so in two ways. During movement your muscles pull sugar from the blood without needing insulin, which is why a 10 to 15 minute walk after meals visibly flattens the after-eating spike. It is one of the cheapest tricks in metabolic health.
What exercise burns the most belly fat?
No exercise burns belly fat specifically. You cannot choose where fat leaves from: crunches strengthen the muscles underneath but do not touch the fat above them. Spot reduction has failed in every study that has looked for it.
Is soreness a sign of a good workout?
No, soreness is not a sign of a good workout. Soreness mostly measures novelty, not quality. A brand new movement leaves you aching for days; the same session two weeks later barely registers, yet builds just as much strength. Chasing soreness just chases newness.
What is a good VO2 max for my age?
For men, the middle of the range is about 48 in the twenties, 42 in the thirties, 38 in the forties and 28 in the sixties, in ml per kg per minute. For women the same decades run roughly 38, 30, 27 and 20. Those come from 7,783 treadmill tests with a mask on, so they are measured rather than estimated.
Can I test my VO2 max without a lab?
Three ways, and they are not equally good. The easiest needs no exercise at all: your age, sex, BMI, resting pulse and how much you move in a normal week go into an equation. It is fine for placing you in a band and poor at detecting change, because none of those inputs move much when fitness does.
What is an average grip strength for my age?
One hand on a dynamometer, best of three. Men peak in their thirties at around 51 kg and women at around 31 kg. By seventy those medians are near 38 and 20, and by eighty near 31 and 15.
Does grip strength really predict how long you live?
For death from any cause, yes, and strikingly well. Across 139,691 people in seventeen countries, every 5 kg weaker went with 16 percent higher all-cause mortality and 17 percent higher cardiovascular mortality.
How many push-ups should I be able to do at my age?
For men from the toes, the reference tables put about 22 in the middle in your twenties and 36 or more in the top band. In your forties that is roughly 13 and 25, and in your sixties 8 and 18.
Is doing 40 push-ups really good for your heart?
The study behind that headline followed 1,104 male firefighters for ten years. Those managing more than 40 push-ups had far fewer cardiovascular events than those managing ten or fewer, and the figure quoted as a 96 percent reduction comes from that comparison.
How long should I be able to stand on one leg?
With your eyes open, essentially as long as anyone bothers to time you until about sixty. The study behind the norms stopped every trial at 45 seconds and nearly everybody under forty reached the cap.
What is a normal walking speed for my age?
About 1.4 metres a second through your twenties, thirties and forties. Men hold that until roughly fifty, then slow to about 1.26 in their sixties and 1.20 in their seventies. Women start slowing earlier, from about thirty, reaching 1.21 and 1.13 in the same decades. Past eighty both sit near 1.0.
Does walking slowly mean something is wrong?
In adults over 65 it is treated as a vital sign. Across 34,485 of them, every 0.1 metres a second faster went with roughly 12 percent lower mortality, in a smooth gradient with no cliff anywhere along it.
What is the sit to stand test and what does my score mean?
You lower yourself to sitting cross-legged on the floor and get back up, starting from ten points and losing one for each hand, forearm, knee or side of leg you lean on, and half a point for a wobble. A ten means down and up with nothing touching but your feet and your backside.
