I need your help! I'm trying to decide whether to move forward with this project given the risks.

I need at least 20 people to pre-order to move forward.

You only have to pay $50 for the pre-order even though I'm planning to sell it for $175.

If I don't move forward, I'll cancel the pre-order and refund you.

Help make HYDRAfit become a reality and be one of our early supporters!

HOw HYDRAfit works

Unlike elastic bands, HYDRAfit provides 0-200lbs of smooth continuous concentric-only resistance.

Why elastic bands don't work

There's no comparison.

Inconsistent resistance undertrains lats, shoulders, and chest and overtrains triceps.

Elastic eccentric jerk prevents training complete smooth swim stroke through recovery stroke.

Only one inconsistent level of resistance.

Elastic loses strech quickly.

how hydrafit improves technique

It's much easier to practice technique on dryland than in the pool.

Record yourself paddling on the HYDRAfit and compare it vs technique videos to pinpoint flaws.


Elastic bands don't effectively train your paddling. They don't train the catch/pull phase adequately and instead mostly work the triceps. They also prohibit you from training the recovery stroke.

The HYDRAfit is not elastic, it uses static rope with a resistance unit that allows you to effectively train the entire paddle stroke including the recovery.

Elastic bands also lose their elasticity over time and aren't durable. The HYDRAfit is much more durable. It takes years to wear down the rope, and you can easily and cheaply replace it.

The recovery stroke is crucial because it's the part of the stroke that fatigues surfers arms the most. Not training it means that you won't be able to paddle for long durations. HYDRAfit is the only compact trainer that allows you to do that.

The recovery stroke returns your hand from the end of the stroke back to the beginning of the stroke and heavily taxes your rear deltoids, rotator cuffs, and traps. These muscles are amongst the first to fatigue during a long paddle session because they are small and not heavily utilized. That burning in your shoulders during long sessions is actually because of the recovery stroke.

No, the HYDRAfit unit applies resistance to the rope as it passes back and forth through the unit.

No, it will not damage your door - the anchor is cloth. Works with any door and installs in seconds.

You can tie the rope anchor to anything and you can also use it with a suction cup wall anchor.

No, you can use it simply use it standing up and laying down. Or you can use an exercise ball if you have enough space for that.

Think of a pull-up. The concentric phase is when you pull yourself up, eccentric is when you lower yourself back down.

The HYDRAfit is concentric-only so it provides resistance during the catch/pull/push/exit phases of the stroke, but no resistance during the recovery stroke to allow you to return your arm back to its starting position.

Besides paddling, the types of exercises that are possible are limited only by your imagination, but here is a list of some important ones: lat pulldown, chest pulldown, chest press, shoulder press, shoulder front raise, shoulder side raise, bicep curl, tricep pushdown, squat, and deadlift.

No, the resistance unit is friction based and requires no energy.

The HYDRAfit is very durable and will last you many years. The rope should also last several years, but you can easily replace it.
