That's usually delayed onset muscle soreness, or DOMS. When muscles work harder than they're used to (a new sport, a big hill, the first session back), they pick up small amounts of strain that the body then repairs. The soreness usually builds over 1–3 days and eases within about a week. It's a normal part of getting fitter.

Common recovery questions
Straight answers on soreness, ice, heat and compression. Tap a card to read the answer.
A common rule of thumb: cold for a fresh knock, sprain or strain, especially in the first couple of days, and heat for muscles that feel tight, stiff or sore after training. Avoid heat on a fresh injury that is swelling. If you're not sure which suits your situation, ask your doctor or physiotherapist. CompressiveX Dual Thermo™ Packs do both: freeze them for cold or microwave them for heat.
Australian first-aid guidance for sprains and strains is about 15–20 minutes at a time, up to every 2 hours while you're awake, for the first 48–72 hours. Protect your skin, check it regularly, and stop if it turns red, numb or discoloured.
RICE is classic first aid for sprains and strains: Rest, Ice, Compression and Elevation. Australian guides pair it with "no HARM" for the first 72 hours: no Heat, Alcohol, Running (or re-injury) or Massage on the injured area. Newer approaches also stress protecting the area early, then getting moving gently as it settles. See a doctor or physiotherapist for anything more than a mild injury.
Studies of compression garments suggest they may help ease muscle soreness after hard exercise, with the clearest effects a day or more later. Compression is also the C in RICE. Fit matters: it should feel snug and even, never tight enough to cause tingling, numbness or a change in skin colour.
Usually, yes, gently. Light movement such as walking or an easy session often feels better than complete rest. Give very sore muscles a break from hard training until they settle, and stop if pain is sharp or getting worse.
See a health professional if you can't put weight on a joint, it looks out of shape, there's a lot of swelling or bruising, the pain is severe or getting worse, or it hasn't improved after a week. Get urgent help for severe muscle pain together with dark, cola-coloured urine.
Quick answers
Common questions about your CompressiveX gear
How long should a hot or cold session be?
About 15–20 minutes at a time. Check your skin every 5 minutes, and take the pack off straight away if your skin turns red, numb or discoloured.
How long do I freeze the Dual Thermo™ Pack?
At least 15 minutes. For the coldest pack, freeze it flat for 2 hours or more. More in the hot & cold therapy guide.
How do I heat the gel pack?
Take the pack out of the brace or wrap first. Never microwave it inside. Heat it in 20-second bursts and check the temperature each time. About 60–70 seconds in total is usually enough, but microwaves vary. It should feel warm and comfortable, never hot.
Can I wear the Knee Brace while I'm active?
Yes. Take the gel pack out first. Without the pack, the brace gives compression and spring-stabilised support for walking, stairs, everyday movement and exercise. It isn't designed for extreme load-bearing or vigorous bending and straightening of the knee.
Where can I use the Recovery Flex Pack?
On your knee, leg or arm. The same wrap fits around the knee, calf, thigh, forearm or elbow, and you can move the gel pack to where you want it. See the Flex Pack guide.
Can the gel pack go straight on my skin?
Yes, if it feels comfortable. If you're sensitive to heat or cold, put a thin towel or cloth between the pack and your skin. Don't use it on open or broken skin.
How do I clean the brace or wrap?
Take the gel pack out, then hand wash in cool water (30 °C or below) with a gentle pressing motion and air dry in the shade. No machine washing, tumble drying, ironing or bleach. Wipe the gel packs clean with a damp cloth.
Is it suitable if I have a medical condition?
Talk to your doctor before use if you have a circulatory or sensory condition, diabetes or reduced skin sensation. Read the full health warnings before you start.
