1. SMALL BICEPS IS NOT YOUR FAULT
Up to 50% of biceps are made out of slow-twitch (Type-1) muscle fibers. Your genetics might be the reason your biceps stay small.
2. WEIGHTED SLEEVES.
BICEP GROWTH ON AUTOPILOT.
Slow progress, lack of time and daunting workouts can make big arms feel like more trouble than they're worth. Not anymore.
3. THE WORLD'S HEAVIEST FABRIC
Absurdly heavy. Surprisingly comfortable. Slim enough to blend in, buttery-soft against your skin, and stretchy like sportswear to move with you.

Stop neglecting 50%
of your biceps
Stop neglecting 50%
of your biceps
More than 50% of your biceps could be made up of slow-twitch muscle fiber (Type 1), but you’re
focusing only on the other half.
To maximize muscle growth you may need to start training your arms as if preparing for a marathon, not a sprint.
Easy
Convenient
Impossible to skip
Lighter weights and higher reps stimulate growth in slow-twitch (type I) muscle fibres. Heavy, low-rep training won't grow them the same way.
This applies no matter your personal ratio*

Small Biceps Is Not Your Fault.
Why Wearing Weight Matters More Than You Think
To efficiently train the slow-twitch muscle fibres in your biceps, you need highly targeted exercises for an extended period of time, which is only possible with a moderately low weight.
The Big Issue & The Reason You Need Natural Resistance
Longer sessions of lightweight biceps exercise can be awkward or better said close to impossible to fit into everyday life. After all, who wants to walk around holding dumbbells all day?
The NR Method
Natural Resistance proposes a new type of training method based on lightweight, high-rep exercise using wearable weights to help you achieve your fitness goal in a more convenient way to exercise.
How It Works
By wearing Natural Resistance throughout the day, you are essentially stacking a very high number of moderately weighted reps / biceps curls throughout your whole day. A total session time that greatly exceeds that of going to the gym! Therefore, this type of exercise more closely resembles that of an endurance athlete rather than a sprinter (which is what weightlifting resembles).
*The type 1, type 2 split is individual and differs between people.

I'm really excited that I received the garments and was able to use them for training - it is super impressive, I was really mind-blown.

I’ve received the shorts, and wow what an amazing material!
It really feels like this material has a lot of potential.

The Hybrid Shorts are great! I came across Natural Resistance on Instagram and liked the concept straight away. I ordered the Hybrid Shorts and tried them on a slow run. They fit snug, look and feel similar to my normal running tights just slightly thicker at the weighted parts. The extra weight is definitely noticeable once you get moving. I would love to see a pocket added for my phone, but overall I’m very happy with them!
