This is the secret to soothing sore muscles during marathon training — and it’s over 20% off on Amazon

I’m two weeks out from running the Berlin Marathon, and my legs are certainly feeling all the miles I’ve put in so far.

After my peak run last weekend, I was craving some relief, so I began browsing the internet for solutions to sore muscles. Stretching and foam rolling are both vital, but contrast therapy has also played a key role in my recovery as well.

According to a study published by the National Library of Medicine, contrast therapy improves circulation, reduces inflammation, provides pain relief and aids in faster recovery.

Alternating between a sauna and a cold plunge is the old-school, tried-and-true method, but it’s not always available. That’s why I was excited to find the BOB AND BRAD ThermArmor 3-in-1 Electric Ice Pack on Amazon, which is now over 20% off.

The device offers different modes of heat (100°F, 104°F, 108°F) and cold (41°F, 50°F, 59°F) to alleviate achiness. In just three minutes, it targets problem areas without the fuss of a dripping ice pack, or needing to wait for a pad to heat in the microwave.

The dual-wing design wraps comfortably around your knees, shoulders, elbows and more, leaving no gaps present. There are three straps — small, medium and large — to customize the perfect fit.

Plus, the compact device is cordless. Stash it in your bag, then wear it out and about. At just 14 oz, it won’t weigh you down.

No need to worry about over-cooling or over-heating. Smart Temp Control ensures the device stays at a safe temperature at all times.

I’m not the only one who’s a fan. One Amazon reviewer praised its benefits for injury prevention: “I have a torn meniscus and the knee swells if I walk too far. But I have been using this regularly after my walks on the contrast mode…. I feel my recovery has been faster and so I am putting off surgery for now.”

Whether you’re training for a marathon like me or simply want to give your body some TLC, you should definitely check out BOB AND BRAD ThermArmor 3-in-1 Electric Ice Pack on Amazon while it’s 23% off for a limited time.
