What is the single best exercise? The squat. If you can only do one movement for the rest of your life, pick the squat. It works the biggest muscles in your body, burns more calories than almost any other exercise, and builds the kind of strength that keeps you moving well into old age.
But here’s the thing. The “best” exercise depends on what you want. Want to build muscle? Squats win. Want to live longer? Strength training beats cardio. Want to lose fat? Walking works better than you think.
Let me break this down.
Why Do Squats Beat Every Other Exercise?
Squats work more muscles than any other single movement. Your quads, glutes, hamstrings, core, and lower back all fire at once. Because they use the largest muscle groups in your body, squats burn serious calories.
A 2016 study found that starting your workout with large muscle groups like your glutes and legs produces the biggest hormonal response. Training legs first early in the week sets off metabolic processes that carry you through the entire week. Your metabolism stays higher, your hormones stay balanced, and your body stays in muscle building mode.
The research backs this up. Compound exercises that use multiple joints and muscles work several parts of your body at once. Squats hit this better than any isolation movement.

Is Strength Training Better Than Cardio?
Yes. For building muscle, losing fat, and living longer, strength training wins.
Here’s why. Your muscle mass starts to decline after age 30. You lose about 3 to 8 percent of it every decade. Your bone density peaks around age 25 to 30, then drops. By 40, the loss speeds up. When you fall as an older adult, your risk of breaking something shoots way up.
Strength training fights both problems. It builds muscle mass and increases bone density. These two things matter more for longevity than almost anything else. Women face higher risk for osteoporosis, but men actually die more often from falls. Building muscle and bone now protects you later.
The numbers on falls are shocking. About 32,000 people die each year from falls, and that number has nearly doubled in the last decade. Muscle mass helps prevent falls and helps you recover if you do fall.
Cardio is great for your heart. But for keeping your body strong and functional as you age, resistance training beats it.
What About Cardio for Fat Loss?
Cardio is not very effective for losing fat. Here’s proof.
Researchers had people burn 2,000 calories per week through cardio. On paper, that should equal about two pounds of fat loss per month. The actual result? Less than half that. Some people lost no fat at all.
Why? Your body compensates. When you burn calories through intense cardio, you move less the rest of the day. You collapse on the couch. Your most intense activity becomes carrying chips from the bag to your mouth. All those non workout activities you normally do, like fidgeting, walking around, and moving, drop off.
Plus cardio makes you hungry. People often eat back all the calories they burned, sometimes more.
A highly active person can burn up to 2,000 extra calories every day just from normal daily movement compared to someone who sits all day. That’s called NEAT, or non exercise activity thermogenesis. Walking, typing, cooking dinner, taking stairs. It adds up fast.
Does Walking Actually Work for Fat Loss?
Walking works better than traditional cardio for fat loss. The research supports this.
Aim for 7,000 to 12,000 steps per day. A 30 minute walk covers about 3,000 steps and burns 100 to 200 calories for most people. Add one 30 minute walk every day and you can lose an extra pound of fat per month without changing anything else.
Walking doesn’t spike your hunger like intense cardio does. It doesn’t wipe you out so you sit around all afternoon. And you can do it every single day without needing recovery time.
The best part? You can stack walking on top of strength training. Do your squats, deadlifts, and presses three to four times per week. Walk every day. That combination beats any single approach.
How Many Days Per Week Should You Lift Weights?
Three to five days works for most people.
For beginners, three days of full body training builds muscle fast. You can add 5 to 10 pounds to the bar every single week when you start. That rate won’t last forever, but ride it while you can.
Keep your sessions under 60 minutes of real work after warming up. Research shows that going past 60 minutes increases cortisol, the stress hormone that blocks recovery.
After about 10 minutes of warming up, aim for 50 to 60 minutes of actual lifting. Rest two to four minutes between heavy sets on big lifts like squats and deadlifts. For lighter exercises, 60 to 90 seconds works fine.
What Rep Range Builds the Most Muscle?
You can build muscle with rep ranges from 5 to 30. The science is clear on this.
But most people get the best results by cycling through different rep ranges. Spend three to four weeks doing 4 to 8 reps with heavier weight and longer rest periods. Then switch to 8 to 15 reps with lighter weight and shorter rest. This prevents boredom and keeps your muscles adapting.
The real key is effort. Most people stop when it gets uncomfortable. Research shows that when you tell someone to leave two reps in reserve, they actually leave five, six, or seven. Push your sets closer to failure and you’ll grow faster.
What Should You Eat Before and After Working Out?
Before your workout, eat protein and carbs about 30 to 60 minutes ahead. Keep the carbs a bit higher than the protein.
After your workout, flip it. Go higher on protein, at least 20 grams. Your muscles need protein to repair and grow.
But don’t overthink meal timing. What you eat throughout the whole day matters more than any single meal. Hit your daily protein target and you’ll be fine. For most people that means 0.8 grams of protein per pound of body weight. If you weigh 80 kilograms, aim for around 140 grams of protein spread across the day.
How Do You Keep Making Progress?
You need progressive overload. Your muscles only grow when you challenge them with more than they’re used to.
Five ways to do this
- Add more weight to the bar
- Do more reps with the same weight
- Add more sets per muscle group
- Slow down your reps to increase time under tension
- Improve your form so your target muscles work harder
When you’re new, adding weight works great. You’ll put 5 to 10 pounds on your squat every week. But eventually you stall. That’s when you switch tactics. Add reps instead. Or add a set. Or slow down the lowering portion of each rep.
The research shows doing at least 10 sets per muscle group per week nearly doubles your gains compared to doing 5 sets. But there’s a ceiling around 20 to 30 sets where you hit diminishing returns. More than that and you just can’t recover.
Do You Need to Train to Failure?
You should train close to failure on at least your last set of each exercise.
Most people undertrain. They stop when the weight feels heavy instead of when their muscles actually can’t move it anymore. Once you hit the point where your muscles physically cannot contract and move the weight, you’ve found true failure.
A good approach is to leave one or two reps in reserve on your first set. Then send your last set to complete failure. This gives you enough volume without burning out early.
The mind muscle connection matters too. If you really focus on contracting the target muscle, making it do the work, you shift the exercise toward building more muscle. Don’t just move weight. Feel your muscles work.
What’s the Minimum Exercise for Health?
150 minutes of activity per week. That’s the baseline.
Research shows 150 minutes of weekly activity can reduce depression and anxiety symptoms by 40 to 60 percent. Compare that to psychotherapy and medications, which typically reduce symptoms by 20 to 30 percent. Exercise works better for mental health than most people realize.
But you don’t need to do it all at once. Twenty minutes a day, five days a week. Or 30 minutes, three days a week. Find what fits your schedule.
The type matters less than you think. Walking counts. Lifting counts. Playing sports counts. Just move consistently.
Does It Matter What Time You Work Out?
No. Work out when you can stick with it.
Morning workouts make sense for beginners because you get it done before life gets in the way. But if you have more energy in the afternoon or evening, train then. Consistency beats timing every time.
One thing to avoid. Don’t train hard when you’re sleep deprived. Research suggests that training after a bad night of sleep can set you up to get sick. Getting sick means missing multiple training days. Better to skip one day and recover than push through and lose a week.
FAQ
What single exercise builds the most muscle overall? The squat. It works your quads, glutes, hamstrings, and core all at once. Because these are the largest muscles in your body, squats trigger the biggest muscle building response.
Can you get fit with just bodyweight exercises? Yes. Pushups, squats, lunges, and planks build real strength. The key is progressive overload. Add reps, slow down your tempo, or do harder variations over time.
How long until you see results from exercise? Strength gains show up in two to four weeks. Visible muscle changes take eight to twelve weeks. Stick with it for at least three months before judging your progress.
Is walking really enough exercise? For general health and fat loss, walking works well. Aim for 7,000 to 12,000 steps daily. But for building muscle and bone density, you need resistance training too.
What if you only have five minutes? Do squats and pushups. These two movements hit the biggest muscles and require no equipment. Five minutes today builds the habit that leads to 20 minutes next week.
Does the order of exercises matter? Yes. Train your biggest muscles first when you have the most energy. Start with squats or deadlifts, then move to smaller muscle groups like arms and shoulders.
How do you know if you’re training hard enough? Your last rep of each set should feel genuinely difficult. If you can easily do three more reps after stopping, you’re not pushing hard enough. True failure means your muscles physically cannot move the weight.
What’s more important, diet or exercise? For weight loss, diet does most of the work. For building muscle and strength, exercise matters more. For overall health, you need both.
While finding the most effective movement matters, so does knowing how many days to train each week, and pairing exercise with nutrition strategies like the 90-30-50 method can accelerate results—work with a personal trainer in Albert Park to build a complete program around the best exercises for your goals.
