When you hear "strength training," you might picture bodybuilders and heavy barbells. But strength training is for everyone. It's carrying groceries, climbing stairs, getting up from the floor, and lifting a grandchild. The stronger you are, the easier everyday life becomes.

The best part? You can build strength at any age. Studies show that people in their 80s and 90s can get stronger with regular training.

Why strength training matters

From about middle age, we slowly lose muscle and strength if we don't use them. Strength training helps:

• Joints: strong muscles support and protect your back, knees, hips and shoulders. Strengthening is a key treatment for back pain and osteoarthritis.
• Balance and falls: strength plus balance training lowers the risk of falls.
• Bones: loading your muscles and bones helps keep bones strong.
• Daily life: getting up from chairs, carrying things, climbing stairs.
• Health: blood sugar, blood pressure, heart health, sleep and mood.

How much should I do?

The World Health Organization and Canadian guidelines recommend muscle-strengthening activities on 2 or more days a week, working all the major muscle groups:

• Legs and hips
• Back and core (tummy and trunk)
• Chest
• Shoulders and arms

Give each muscle group a day of rest between sessions, for example Monday and Thursday.

The basic recipe for beginners

• Exercises: 6 to 8 exercises that cover your whole body.
• Repetitions ("reps"): 8 to 12 times for each exercise. If you're older or very new to exercise, 10 to 15 lighter reps is a good place to start.
• Sets: start with 1 set of each exercise. Over a few weeks, build up to 2 or 3 sets.
• Rest: take 1 to 2 minutes between sets.
• Effort: choose a weight, band or version of the exercise that feels challenging by the last few reps, but you could still do about 2 more with good form. On a scale of 0 to 10, aim for about a 5 to 7 ("somewhat hard" to "hard").
• Speed: move slowly and with control, taking about 2 to 3 seconds to lift and 2 to 3 seconds to lower.

Something you can do today: Try 10 sit-to-stands from a sturdy chair. Use your hands if you need to.

Good form

• Quality over quantity. A few good reps beat many sloppy ones.
• Breathe. Breathe out as you lift or push, and in as you lower. Don't hold your breath, especially if you have high blood pressure or heart disease.
• Move through a comfortable range. You can make the range bigger as you get stronger.
• Keep it steady. Use a wall, chair or counter for support if you need it.
• Ask for help. A physiotherapist, kinesiologist or qualified trainer can check your form. Our follow-along videos show form cues too.

Simple exercises to start with (no gym needed)

Legs and hips

• Sit-to-stand: stand up from a sturdy chair and sit back down slowly.
• Wall slide or mini-squat: back against a wall, bend your knees a little, then straighten.
• Step-ups: step up onto the bottom stair, holding the rail.
• Side leg raise: holding a counter, lift one leg out to the side.
• Heel raises: holding a counter, rise up onto your toes and lower slowly.

Upper body

• Wall push-ups: hands on a wall, bend your elbows to bring your chest toward the wall, then push back.
• Band rows: loop a resistance band around something sturdy and pull toward your body, squeezing your shoulder blades.
• Overhead press: with light weights or full water bottles, press up overhead, if your shoulders are comfortable.

Back and core

• Bird dog: on hands and knees, reach one arm forward and the opposite leg back, hold, and switch.
• Bridge: lying on your back with knees bent, lift your hips, then lower slowly.

Programmes such as the AAOS conditioning programs, the Otago exercises and the McGill "Big 3" in our exercise library use many of these moves.

How to progress safely

When the last reps start to feel easy (say, you could do 3 or more extra), it's time to make it a bit harder. Change one thing at a time:

1. Add reps, up to 12 to 15.
2. Add a set.
3. Add a little weight, or use a stronger band. Then drop your reps back to 8 to 10 and build up again.
4. Make the exercise harder, such as a lower chair, or less hand support.

Small, steady steps work best. Most people notice they are stronger within a few weeks, and it keeps improving over months.

What about soreness and pain?

• Muscle soreness a day or two after a new or harder workout is normal. It usually fades within a few days, and gets less as your body adapts.
• Joint or back pain during exercise is often okay if it stays mild to moderate and settles within 24 hours. See our guide Pain during exercise.
• Stop if you get sharp, sudden pain, a "pop," or new swelling.
• Stop and call 9-1-1 for chest pain, severe breathlessness or feeling faint.

Special situations

Strength training is safe and helpful for most people, including those with arthritis, heart disease, diabetes and osteoporosis, but it may need adjusting. Talk to your care team or a physiotherapist first if you have:

• Heart disease, high blood pressure that isn't controlled, or recent heart problems
• Osteoporosis, especially if you've had a spine fracture (some bending and twisting moves may need changing)
• A recent injury or surgery, such as a joint replacement or hernia repair
• Eye conditions where straining is a concern

Something you can do this week: Pick 4 exercises from this page and do 1 set of each, twice this week.

Questions to ask your care team

• Is strength training safe for me? Are there any exercises I should avoid?
• How heavy should I go, and how do I know when to progress?
• Can you check my form, or refer me to someone who can?
• How should I adjust exercises for my back, knee, hip or shoulder?
• Do I have osteoporosis or another condition that changes how I should train?
