What’s the Difference Between Rehab and Strength Training?
Rehab and strength training can look very similar from the outside. Both might involve weights, bands, machines or bodyweight exercises, but there is an important difference in their purpose.
STRENGTH TRAINING is primarily about progressively building physical capacity: getting stronger, producing more force, tolerating more load and preparing your body for the demands of life, training or sport.
REHAB is there to help you get back to doing that. It should complement your training or life, not become an entirely separate workout (or chore) that leaves you too sore to train or work.
For me, a good rehab exercise needs to have a clear job.
At By Design, we often think about this through our 3 C’s: Capacity, Coordination and Connection. We might build capacity in an area that needs more work (or settle something that’s currently sensitive), improve coordination of a movement or skill, or rebuild connection and confidence with something you’ve been avoiding.
That could mean a small exercise in your warm-up, a movement between strength sets, graded exposure to a position you’ve been nervous about, or a relief strategy that allows you to move more comfortably.
If we can’t explain what an exercise is trying to achieve, it’s worth questioning why it’s in the program…
This is also why rehab doesn’t necessarily need to destroy you. You might feel a local muscle working hard or experience fatigue during an exercise, but significant soreness the next day isn’t automatically evidence that it worked.
If your rehab repeatedly leaves you too sore or fatigued to complete your normal training, sport or daily activity, we may need to reconsider the dose. Sometimes the best rehab exercise is the one that quietly sits inside your existing training and helps you do the bigger things better.
The same applies to hands-on treatment. Painful treatment isn’t automatically better treatment. Massage, manual therapy, needling, cupping, taping, heat and other strategies may sometimes be used to help modify symptoms, but making treatment increasingly uncomfortable doesn’t prove that we’re creating more change.
Relief can be useful, particularly when it helps someone move or train more comfortably, but ideally it creates an opportunity to then address the movement, strength, capacity or confidence that matters longer term.
Another common misconception is that more rehab exercises means better rehab. I would much rather give someone one exercises with a clear purpose and they can do well, than a huge list they don’t understand and won’t consistently complete. This is actually a big principle of ours!
Rehab should evolve too. Once an exercise has achieved its job, we progress it, integrate it into normal training or remove it. You shouldn’t still be doing the same collection of ‘corrective’ exercises forever simply because you were once given them for an injury. Rehab should have an end point.
Ultimately, the goal of rehab isn’t to become really good at rehab. It’s to help you get back to training, running, sport, work or whatever else matters to you.
Good rehab should have a purpose, fit around the rest of your life and progressively become less necessary as your capacity and confidence return. The end goal isn’t an endless collection of exercises. It’s getting you back to doing more of the things you actually want to do.
If you’re managing an injury and aren’t sure whether your current exercises are actually moving you towards your goals, book an appointment with the By Design Physiotherapy team.
This is general information only. If you’re managing pain or an injury, speak with your physio about what’s right for you.
