Cold immersion can help reduce muscle soreness and inflammation by constricting blood vessels and flushing out metabolic waste, speeding up post-workout recovery.
Alternating between cold exposure and rewarming stimulates blood flow, helping promote better circulation and overall cardiovascular health.
Regular cold plunge can boost immune function by increasing white blood cell production, helping the body fight off illness and inflammation.
Cold therapy naturally lowers cortisol levels which can lead to a more effective way to de-stress.
Exposure to cold activates brown fat which can help burn calories and regulate body temperature, leading to a natural metabolic boost.
Cold plunges trigger release of endorphins and dopamine which can enhance mood and promote a sense of well-being.

Purchased the RTM Wall Mounted Pull Up Bar from Cardio Online. Compact, easy to install product with great functionality. Rated up to 150kgs, I'm only 80kgs and the quality feels all good - but would probably not put much more than 100 - 110kgs onto the bar. Good grip padding and ideal for a home gym. Would recommend it :)
It is a great product
I am using it for 4 days now as I received it last Saturday
It helps me to be active
It's been 3 days and everything is good so far. Shipping is good too.
Shipping was brilliant. The gentleman was wonderful and very helpful in getting it off. My husband assembled it, and everything worked and looked great.
It’s good so far. I’ve been using it for three days now and it’s fitting well into my routine.
