Why Your Body Feels Different When You Start Exercising Again in Spring

When the days start getting longer and the weather improves, many people naturally begin moving more again. Evening runs return, weekend sport becomes more appealing, and activities that felt less inviting during winter start creeping back into the routine.

For many people this is a welcome change. But it’s also quite common to notice new aches appearing around the same time — a tight calf after a run, a sore knee after football, or a stiff lower back after a round of golf.

This doesn’t necessarily mean something has gone wrong. Often it’s simply the body adjusting to a sudden shift in activity after several quieter months.

What changes over winter

Even people who stay reasonably active through winter often move differently compared to spring and summer.

Outdoor sport may reduce, running distances often drop, and many activities become less frequent. Over time the body adapts to that lower demand. Muscles, tendons and joints are still functioning normally, but they’re no longer exposed to the same level of repeated stress they might have experienced during more active periods of the year.

When activity returns quite quickly in spring, the body is sometimes asked to handle loads it hasn’t experienced for a while.

Why symptoms often appear in the first few weeks

When tissues are exposed to a new or increased physical demand, they need a short period to adapt.

During that adjustment phase it’s quite normal to notice areas that feel tight, fatigued or slightly irritated. Common examples we see in clinic include:

• Calf and Achilles soreness in people returning to running

• Knee discomfort in football or rugby players

• Shoulder irritation in tennis players

• Lower back stiffness after rotational sports like golf

These issues are often linked less to a single movement and more to the overall change in activity patterns.

The role of movement habits

Another factor that becomes more noticeable when activity increases is how the body distributes load during movement.

If certain joints or muscles are slightly restricted or weaker than others, nearby structures may end up doing more work than they should. During quieter periods this often goes unnoticed.

Once training volume increases, however, those patterns can start to produce symptoms.

That’s why two people can follow the same training plan yet only one develops a problem — individual movement patterns and previous injuries often play a role.

A steadier way to rebuild activity

For people returning to sport after a quieter winter, the goal usually isn’t to hold back from activity completely. Instead, it’s about allowing the body time to rebuild tolerance.

Some simple adjustments can make this transition easier:

• Build training time or distance progressively over several weeks

• Alternate harder and easier sessions while returning to sport

• Include some basic strength or mobility work alongside activity

• Pay attention to persistent tightness that doesn’t settle after rest

Small changes in progression often make a significant difference to how the body responds.

When it’s worth getting something checked

Occasional soreness after exercise is normal, particularly when activity levels change. However, it can be useful to have symptoms assessed if they are continuing to build, returning every time you train, or starting to affect performance.

At Coventry Osteopaths, this type of assessment may be carried out by an osteopath or a sports therapist, depending on the nature of the problem and the type of activity involved. Both focus on identifying how the injury developed, what structures are under strain, and how activity can be progressed safely while the area settles.

That broader view can help explain why symptoms are appearing and what may help reduce stress on the affected tissues as activity levels increase again.
