How to keep training when your joints and energy are unpredictable

I recently had a workout where the first warm-up set felt fine, but the next one didn’t. My shoulder started to complain, and my energy held up only for a while before fading. The older version of me would have either forced it or abandoned the session and gone for a walk.

Neither approach helps much.

I’m in perimenopause, and I coach women who are, too. Uneven weeks are common. A movement that feels stable one day can feel irritating the next. Sleep may be good, yet the workout still feels heavier than expected. That doesn’t mean strength training is failing; it usually means that session needs adjusting.

This is the part many people overlook. They wait for the perfect week, when everything feels easy. That’s like waiting for Santa when it isn’t Christmas. The real skill is showing up and adapting, not forcing the exact same workout every time.

How to tell what you’re dealing with

Start with one question: is this a day for modification, or a day to skip that lift?

A modification day often feels like stiffness, a dull ache that improves as you warm up, low energy, or a cranky joint that can still work with a smaller range or different setup. You can still move well. You just can’t pretend it’s the same as last week’s session.

A skip-that-lift day is more serious. Pain gets sharper as you continue. Swelling appears. One side clearly worsens instead of easing up. If every version of the movement hurts sharply, do not keep searching for a way to force it. Train a different lift and leave that one alone.

For most people in perimenopause, the day is usually the first kind. Treating those days like the second can cost weeks of training and gains that didn’t need to be lost.

How to modify a session

Good modification means changing the smallest thing possible while keeping the point of the lift. Work through these steps and stop as soon as the movement feels manageable.

Warm up longer than you think you need. Add an extra easy set. If energy improves or pain settles, build from there instead of starting where you normally would. If not, move down the list.

Reduce the range before dropping the exercise. A full squat can become a demi squat, or half depth. A press can stop just short of the bottom position that irritates the shoulder. You still train the pattern. Hand or foot placement can also help.

Slow the tempo. Fast, sloppy reps tend to annoy irritated joints. Controlled work often makes the lift stay possible.

Lower the load and keep the movement. Using less weight does not mean you are going backward. You can build it back up once the joint settles.

Use a close variation. If a full push-up bothers your shoulder, do it with your hands on a bench or countertop so you do not go as deep. If a deadlift irritates your back, raise the weights on yoga blocks or a low step and hinge only as far as you can without pain. If walking lunges bother your knee, stay in place with reverse lunges or switch to step-ups on a stair.

Cut extra sets and extra exercises before canceling the entire session. Keep the main work and trim the rest.

Shorten the session if energy is the problem rather than a joint. Two solid sets of your main lifts are better than a long workout you have to talk yourself through.

Use this as a guide instead of rewriting your whole program whenever something feels off. Choose the version you can do well that day.

What this looks like in real life

On a cranky-shoulder day, I do not need a brand-new plan. I need a pressing option that doesn’t make the problem worse. On a low-energy day, I do not automatically need a rest day. I need fewer sets and a shorter work window. On a hip-flexor day, I keep the squat pattern and adjust depth or position instead of deciding squats are off-limits until further notice.

The biggest mistake I see is all-or-nothing thinking. People either push through sharp feedback or disappear until they feel 100% again, and both choices cost momentum. The middle path is less dramatic and far more useful: keep the intent of the session and change the delivery.

If a joint stays irritated across several sessions even after these changes, that is a sign to get it checked. Modification is a tool, not a way to ignore a real problem.

Do this next time you train

Before you begin, choose your main lifts and decide in advance what the backup version will be. That way, you won’t have to make the decision while you are already frustrated. Warm up a little longer than usual. Ask one question: What version of this can I do well today? Do that version and call it a day.

Although this is the third article in my perimenopause series, the advice also works for men and for lifters of any age.
