Use This Trick to Build Strength When It Hurts to Move

If joint pain or stiffness is getting in the way of your workouts, we’ve got a tip that could be a game changer.

It’s something we use with our members at Mint Condition Fitness all the time, and it’s especially helpful for anyone over 50 who wants to stay strong without making their pain worse.

It’s called an isometric.

What’s an Isometric?

An isometric exercise involves activating your muscles without actually moving the joint.

You create force, build strength, and engage key muscles, without aggravating joint pain or moving into a painful range of motion.

That’s what makes isometrics so valuable for people dealing with:

  • Arthritis or joint inflammation
  • Range of motion limitations
  • Post-surgical recovery
  • Chronic pain that flares with movement

And just because you're not moving doesn’t mean you're not working. Isometrics can still challenge your muscles and help you make serious progress.

In this week’s video, Coach Bradley walks you through exactly how to use this type of exercise:

3 Isometric Exercises You Can Do Today

Here are the three isometric exercises discussed in the video above:

1. Squat Hold

This is a great lower-body isometric exercise that targets your quads and glutes while keeping the knees safe.

  • Stand with feet shoulder-width apart
  • Toes forward or slightly turned out
  • Sink into a squat, going only as low as you can without pain
  • Keep your chest tall and abs engaged
  • Hold for 30–60 seconds

If you have trouble squatting or need more support, try a wall sit instead. You’ll still build strength in the quads with less joint demand.

2. Elbow Driver

This one looks easy, but don’t be fooled. It’s a powerful move for your back, shoulders, and core.

  • Lie on your back with knees bent, feet flat
  • Press your elbows into the ground as hard as you can
  • Try to drive your elbows “through” the floor
  • Focus on squeezing your shoulder blades and engaging your abs
  • Hold for 30–60 seconds

This is a great way to wake up your postural muscles and improve body awareness.

3. Plank + Anti-Rotation Progressions

The classic plank is already a great isometric, but we like to build on it with a few safe but challenging variations.

Start in a plank on your elbows and toes:

  • Level 1: Hold the plank, focus on keeping a straight line from head to heel
  • Level 2: Lift one leg without letting your hips shift
  • Level 3: Lift one arm
  • Level 4: Lift the opposite arm and leg

Each level increases the anti-rotation demand, which means your core has to work harder to keep you stable. Go at your own pace and only progress once you’ve mastered the current level.

How to Use This Workout

Try this isometric circuit:

  • Squat Hold – 30 to 60 seconds
  • Elbow Driver – 30 to 60 seconds
  • Plank (choose your level) – 30 to 60 seconds
  • Rest – Take a 1 minute break
  • Repeat – Go through circuit 2 more times

That’s just 12 minutes, and you’ll feel like you did something worthwhile without irritating your joints.

Why This Works for Adults 50+

As we age, staying strong becomes even more important, but doing it safely is the key to long-term success.

Isometrics offer:

  • A way to build strength without harmful joint movement
  • A safe method to challenge muscles while protecting recovery
  • A path back to training even when traditional exercises feel off-limits

They’re not a replacement for all movement, but they’re an incredible tool for rebuilding strength, especially during periods of pain or restriction.
