I began using the "O" model when it was a proof of concept and have had 2 iterations of this board. My review will be based on the current O model. Here's a little about me for perspective:

I am 46 years old and live in Boulder Colorado, and weigh about 152 pounds. I use my Surfinshape at our local gym, Rallysport, who are very welcoming and supportive of an alternative training tool in their pools. All of my surfing occurs on surf trips since I am landlocked. I strive to do at least 1-2 trips a year, which typically are anywhere from 5-10 days, and almost always in Central America. I feel like surfing is a lifetime of learning for me and I try to learn something new about my progress each and every trip. I did not grow up surfing but did learn the basics from my vacations in the Carolinas as a teenager, where each summer we spent two week on the coast. My current board is a Proctor Monsta, 5'10" 19.5 x 25 31L. Surfinshape has allowed me to build my paddle strength to be able to enjoy my surf trips to the fullest extent.

Durability:
I have been paddling on the current "O" model since 2017. Other than some discolorations on the board, everything looks great and the board looks almost new with virtually no indentations in the foam. The blue deck pad on top looks almost new with only a scratch in the foam from where I left board leaning against something with a sharp edge in my truck. I feel like the construction of this board is of very high quality (With attention to detail-Titanium screws for bucket) and it will last you for years and years, given that you exercise basic common sense as you would a regular surfboard.

Paddle fitness:
Prior to an upcoming surf trip, I try to get into the water at least 6-8 weeks prior to my trip, and work up to about a mile per pool session of paddling, 4-6 days a week. I just returned from Costa Rica and only spent 3.5 weeks in the pool before my trip, and was doing about 5 sessions per week, at a mile per session. On this trip, I surfed 2 sessions per day for 9 days straight. I felt amazing on my first day in the water and was able to paddle out to the lineup with little fatigue and catch waves without being destroyed from paddling. Throughout my trip, I consistently felt strong paddling and this allowed me to focus on technique and improvement, as opposed to constantly being fatigued when out in the lineup, or even worse, not being able to make it back out when you get caught inside, as we all know that this is inevitable. Without paddling fitness, it's tough to enjoy your trip and most will fatigue after 2-3 sessions in the water when on a trip. Some would argue, why not just swim in the pool as opposed to using a Surfinshape? As an avid skier and cyclist, I understand that you need the right tool for the job. Swimming in itself can and help you prepare for a surf trip, but it simply no match for what Surfinshape can do for your paddling, and does not target the same muscles. With Surfinshape, you can replicate paddling and proper technique, add resistance paddling, improve your balance on the board, and even practice duck diving. None of this can be achieved from swimming in the pool without Surfinshape. Surfinshape targets the exact muscles, nerves, and balance necessary for a great surf trip. Additionally for me, while paddling in the pool, I frequently visualize myself paddling out to the the lineup and making it over that rogue set wave, and even paddling to get that perfect right of left, which adds to the fun while training. There's not much worse (Well...no surf could be worse) than not being fit and properly trained for your coveted, long anticipated surf trip.

For me, surfing is a lifelong learning experience and Surfinshape lends to the ability for me to improve. Without Surfinshape, I would never have been able to make the progression to a shorter, performance oriented board. Surfinshape has made the difference for me 110% and is an absolute game changer. I can't say enough about how much Surfinshape has done to help my surfing. Thank You Jay!!

I am not able to surf all the time. When I go I would tire out easy, and struggle on bigger days. This is definitely going to help with all of that! I can’t wait to see how I feel paddling after training for a while. I highly recommend this board :) happy shredding 🏄‍♀️

I started surfing later in life , with no swimming background. In order to make up for lost time, I have been taking it seriously, trying to get fit on land or in the pool, conditioning, swimming, training. Whenever I would go on surf trips, I always ended up disappointed when I got to the ocean; I felt I was not quite prepared specifically for surfing. I felt my paddling was weak and it would take a week or two before I felt comfortable in the ocean. At the end of last year, I started training with my Surfinshape board before a trip to Salvador. When I got there, my first session felt like I had been surfing for weeks ! Surfinshape is an amazing training tool that helps me make the most of my time in the ocean, I love it !

When I had to move from CA to Pittsburgh, PA for work, I didn't know how I'd be able to stay in shape to surf. Every vacation or weekend I have off, I'm flying somewhere to score some waves. With only 1-2 opportunities to surf every month or 2, my first session was always wasted struggling to catch waves. After my paddle strength would come back after a few sessions, my trip was usually over. After discovering Surfinshape, I've been keeping fit by paddling 3x/week. I have a small indoor pool in my housing complex which allows me to train year-round. It's a small pool so I'm often doing 100+ laps but I put on some AirPods and listen to audiobooks while I paddle. Last year I had the opportunity to surf at "Kelly's wave" at the Surf Ranch in Lemoore, CA. With each wave valued at hundreds of dollars, I was nervous I wouldn't be able to catch them! With Surfinshape, I didn't miss a single wave and had no problem poaching waves last minute when others fell. Jay has also gone above and beyond with customer service. When I emailed him that the resistance was too weak, he sent me some extra buckets to really increase the resistance. I'm beyond happy with this trainer. If you can't surf regularly to keep your paddle strength up, this is the next best thing!!! Aloha, Mike!

I’m 36 years old and started surfing three years ago.I live in Madrid, far from the beach so up to now I have had to settle to go only a couple of weekends a month. Obviously is not sufficient. I usually get tired very soon and couldn’t catch any wave. I tried all kind of surf training, Crossfit, TRX, a personal trainer… but nothing worked. Then I tried with SurfingShape. I bought it last year and use it 4 days a week. It’s FANTASTIC. It increased my endurance and paddling strength. Now I can enjoy my surf sessions!! Thank you very much!!!
