So why does it happen?
The technical term for it is DOMS (delayed onset muscle soreness).
When we exercise, we create micro-trauma on the muscle filaments.
Consequently, the body tries to heal the area by sending more blood with nutrients, not to mention that this causes a minor inflammation.
The excess of blood in the area and the inflammation peak 48 hours after a session, and then after that, the pain usually goes away.
To minimise it, you can apply ice, have a cold shower, go for a walk and drink a lot of fluid.
And a bit of massage helps too!

We all have that moment after a workout where everything hurts.
