Physical activity vs. exercise: what's the difference?
Physical activity is any movement through your day that uses energy: walking, yard work, cleaning, dancing in the kitchen.
Exercise is physical activity that's planned and structured: a walk you schedule, a bike ride, a strength session.
Both matter, but exercise (the intentional kind) is what drives most of the benefits below.
Why movement matters
Benefit | How it helps |
Muscle preservation | Protects the lean mass weight loss puts at risk |
Metabolism | More muscle means more energy burned at rest |
Blood sugar support | Muscles pull glucose from the blood as you move |
Bone health | Loading your bones keeps them dense and strong |
Longevity | Better heart health, mood, sleep, and stress |
Weekly guidelines (CDC, for adults)
150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity
Strength training 2x per week
Resistance training
Working your muscles against resistance in time you set aside for it: a dedicated 30–45 minute block you schedule, not movement that happens incidentally through your day.
Sets, reps, and rest: inside that block, you do a set number of repetitions, rest, then repeat, deliberate and controlled. For example, 3 sets of 12 squats with 3-5 minutes of rest between sets.
Why it's a priority on a weight-loss plan
It's the strongest defense against losing muscle as you lose weight
Keeping muscle keeps your metabolic rate up, which protects your results
Loads your bones, supporting bone density and joint stability
Builds the strength and balance that keep you independent for decades
Ways to do it
Body weight exercise · Dumbbells · Resistance bands · Machines · Pilates · Power yoga · Barre
Aerobic training
Continuous, rhythmic movement that raises your heart rate and keeps it there. Moderate means you can talk but not sing.
What it does for you
Strengthens your heart and lungs, and lowers blood pressure
Improves insulin sensitivity and blood sugar control
Builds endurance, so daily life feels easier
Lifts mood and sleep quality, and eases stress
Ways to do it
Brisk walking · Cycling · Swimming · Hiking · Elliptical · Stair climber · Dancing

Do what you enjoy: the movement you'll repeat is the movement that works. Ask your Health Coach where to start.
