Hello, my friends!
Last weekend, I took my baby to two trick-or-treat events for her first Halloween. We had so much fun!
Whenever I'm out in public like that, I have this habit I can't seem to turn off: noticing how people move.
I notice how they walk, carry their kids, get out of cars, or stand up from chairs. I promise I'm not judging anyone. It's just the physical therapist in me!
Those ordinary movements take more strength than we realize.
I've helped patients recovering from illness or surgery regain something as simple as standing up from a chair. Sometimes, a few carefully chosen exercises make a real difference.
So, how much strength training do we need to keep doing these things? The latest research gives us a practical starting point.
Two days a week is a good target
In 2026, the American College of Sports Medicine published an updated review of strength-training research, bringing together 137 reviews involving more than 30,000 adults.
Its main recommendation for healthy adults is straightforward: train your major muscle groups at least twice a week, with exercises that challenge them.
Think legs, hips, back, chest, shoulders, and arms.
And you have options. Dumbbells and gym machines work, of course. So do resistance bands and exercises that use your own body weight. Squats, push-ups against a kitchen counter, and rows with a resistance band all count.
Walking, cycling, and other cardio activities are wonderful for your health. Strength training adds a different kind of challenge that helps your muscles get stronger.
The benefits go beyond stronger arms or legs. Researchers have also found improvements in things like balance, walking speed, and getting up from a chair.
This picture from the study shows how strength training can help with everyday movement, too.

The important part is the challenge.
By the last few repetitions, an exercise should feel like work, while you can still move with control. Your ideal amount also depends on your experience, health, and goals.
Why I tell beginners to focus on showing up first
Every January, I see people who are excited to start exercising and go all-out on day one.
A day or two later, their muscles are so sore that sitting down, taking the stairs, or even thinking about another workout is miserable.
That soreness has a name: delayed-onset muscle soreness, or DOMS. It's especially common after an unusually hard or unfamiliar workout.
No wonder returning for session two can feel daunting.
That's why I encourage beginners to focus on showing up and getting comfortable first.
Learn a few movements.
Practice good form.
Try an amount you can recover from.
If you're unsure where to start, a qualified coach, beginner-friendly class, or well-designed fitness app can help.
You can challenge your muscles without completely exhausting them. And soreness isn't proof that a workout worked.
How to get stronger over time
Your muscles adapt to the work you give them. A squat that feels difficult today may feel easier in a few weeks.
When that happens, you can add a few repetitions, try a slightly harder version, use more resistance, or add another set.
That gradual increase helps you keep improving.
The 2026 review also found that more targeted training can produce additional results. Heavier weights can help people build greater maximum strength. Doing more total sets each week can be useful if your goal is to grow bigger muscles.
A simple two-day routine can build useful strength. Sports or substantial muscle-building goals may call for a more structured plan.
Recovery matters, too.
Your body needs time to adapt between challenging sessions. Beginners can put a rest day between two full-body workouts and enjoy lighter movement in between.
Making room to get stronger again
Before pregnancy, I used to strength train three times a week, and having gym equipment at work made that easy. After becoming a mother, working out at home helped me keep moving.
But now that my daughter is crawling everywhere and learning to walk, she wants to play right underneath me while I exercise. Using dumbbells around her doesn't feel safe, and I've been itching to challenge myself more.
So last week, I tried a gym with childcare.
I was nervous about leaving her there at first, but on our second visit, she seemed comfortable with the staff, and I finally got to enjoy a fuller strength-training session.
I'm excited to see how this arrangement works for us. I'm building the body for my new life now, and finding a safe place to train is part of that.
PROOF & PRACTICE
The proof: Research supports challenging all major muscle groups at least twice weekly, even with simple equipment at home. Gradually increasing the difficulty supports continued progress. Bigger strength or muscle-building goals may require more training.
The practice: Pick two days this week when you could practice strength training. Start with a few movements that cover most of your body:
Sit down and stand up from a chair, or do squats.
Bend at your hips and lift a manageable backpack or weight.
Push against a wall, counter, or the floor.
Pull a resistance band or do rows with a weight.
If you're brand new, even 5–15 minutes can help you learn the movements and get used to showing up. Build toward two fuller sessions of around 20–35 minutes, using resistance that feels increasingly challenging as you improve.
Longer or more structured workouts may make sense for bigger strength or muscle-building goals. These times are practical examples, not magic thresholds.
If you're recovering from injury or surgery, have a medical condition, or are recently postpartum, consider individualized guidance. When you're ill or need recovery, rest is appropriate.
I'm hoping this new gym arrangement works out for us. It feels good to have a chance to lift weights again, and I'll let you know how it goes!
I'd love to hear what strength training looks like for you these days. Do you go to a gym, work out at home, or do something else?
Hit reply and tell me.
To everyday strength,
