Zone 2 specifics
Why an elevated heart rate isn't always the same

Thank you Altra!

New customers can get 10% off your entire order with code jason10 here. I've been wearing Altra shoes for years - I absolutely love the roomy toe box that leaves extra room for my feet to move more naturally.

And these shoes look distinct compared to other shoes: they're shaped like actual feet. They can give your feet just what they need, especially if you want a roomier toebox because of bunions or a hammer toe, or just wanting more comfort.

Altra shoes aren't just zero-drop anymore, either. They have 4mm heel-toe drop models and I've found that this is my personal sweet spot. I love shoes that have between 4 and 8mm so the FWD Via 2 are quickly becoming my favorite pair.

And plus, I do actually like the 0 drop Altras for walking and casual wear - like a quick trip to the grocery store. They're a training tool to help me build foot strength, promote a more natural gait, and give my foot the room it needs to expand naturally.

I've partnered with Altra to get new customers 10% off your next order. Go to Altrarunning.com and use code jason10 to save 10% today. Stay out there!

"My ankle and knee pain was completely gone in a week. Amazing!" - Kim

"I thought I was on the verge of having to give up running due to severe hip pain and luckily discovered Previnex - complete game changer for me!" - Anna

"I am so grateful for Joint Health Plus! As a certified fitness professional and still an extremely active, competitive amateur athlete, I was getting discouraged with an increase in pain simply kneeling down, or bending down to the floor and getting back up while assisting clients, or in my own training! Once deciding to give this product a try, I was floored when I finally noticed I was not bracing in anticipation of pain when I had to kneel down; not whincing in discomfort upon standing! Thank you, Prevenix!" - Jessica

Joint Health Plus is so powerful because the main active ingredient is clinically proven to reduce joint pain, reduce joint stiffness, and improve joint flexibility in just 7-10 days. It's also clinically proven, not just tested, but actually proven in double-blinded, placebo- controlled studies to protect joint cartilage from breaking down during exercise.
