Not a fan of the predatory "Sign up for a 7 day free trial, and if you forget to cancel we'll bill you $60 for the year membership" system. It's also a week trial, but the AI takes 8 workouts to learn -- not great for a comprehensive demo at all.
Jakemor, I noticed you haven’t responded to anybody asking you more than a generic question about your methodology.<p>Here’s what it looks like you did;<p>Made a weight lifting logging app and charged a monthly subscription for it.<p>Used your users data to create an algorithm that culled the routine of your best performers, most likely defined by heaviest weight lifted.<p>Claimed that by following your algorithm your users could 2x the results of trainers; trainers here is defined as “people who train,”
And not “people who are paid to train others.”<p>Cited 60 days as a window of success.<p>All of this, if it is as it appears, is massively misleading in an industry already known for snake oil.<p>Have you compensated for your users that had big numbers but approached it in an unhealthy way? For instance, how many of your user’s deadlift high numbers resulted in a hernias?<p>Additionally you say you have engineers and scientists working on hacking human performance. What about strength and conditioning coaches? What about athletes?
You want my phone number AND "This app does use third party services that may collect information used to identify you."<p>I'm not so comfortable with that. Can you tell us more?
There seems to be a lot of shade here and I wanted to offer a different perspective. I've strength training for over 10 years and aside from the basics like nutrition, rest, form, etc... one of the most valuable tools I use are progression spreadsheets like this one: <a href="https://docs.google.com/spreadsheets/d/1VYNuMhonQw1SOKO_7IbGubON1KxCgCUVxRtef0gQgCM/edit" rel="nofollow">https://docs.google.com/spreadsheets/d/1VYNuMhonQw1SOKO_7IbG...</a><p>The main value is that it not only tells you what exercises to do, but also how much <i>more</i> to lift each day to ensure steady growth. They are designed by well-informed people with a lot of experience in the field. However, there are some major flaws (e.g Most are just linear increases, they don't handle plateaus/failures well, they aren't personalized, exercises don't change, and the UI is pretty bad).<p>There's a lot of potential in something like fitnessai to address these issues. Obviously, it's not going to do everything for you and won't replace your own research and experimentation, but I can see it being super valuable as a tool in the gym.<p>@jakemor the app looks dope. Listen to your customers and keep building it out. The majority of HN may not your ideal customer but don't let that deter you.
> FitnessAI is so simple your grandma can use it.<p>This is a terrible cliche. (More: <a href="https://geekfeminism.wikia.org/wiki/So_simple,_your_mother_could_do_it" rel="nofollow">https://geekfeminism.wikia.org/wiki/So_simple,_your_mother_c...</a>)<p>How about something like:<p>* Your lifts should be hard, your tracking should be effortless. Record your set with a single tap and spend your rest recovering for the next (...or taking selfies, we don't judge).<p>This tells people exactly what the value is and tells the that the user that they deserve FitnessAI.
Fellow hackers,<p>After collecting an insane amount of data with my app Lift Log, I decided to design an algorithm that optimizes for accelerated muscle growth over a short period of time.<p>It currently outperform human trainers by 1-2x in the first 60 days of training, using a very simple algorithm. The opportunity to change how people, athletes, and soldiers train is huge.<p>We're cashflow positive, raised a small seed, and are hiring data scientists & engineers in NYC to hack the human body for efficiency.<p>Hope to answer any questions you may have!
I'm not entirely sold.<p>Fitness magazines assert they can get me bigger, faster in every month's issue. It's a big industry.<p>Perhaps you can post a bit more on the Blog to establish credibility.
is there ANY science behind this? did you take into account weight, height, weather, diet, mood, sleep time, gender, prior experience, age, stress levels, drug consumption, proteins... I could go on..
I came to the comments expecting a lot skeptics and was nos let down. Guys give this a try, I fit the usual software engineer physical stereotype and would like to gain some muscle but I don’t invest that much on PT as i should.<p>IMO, Give this a try jakemor said in the comments he’ll give a free month to anyone on HN
In various places on the webpage, it brags about the design, and how you can do things with "only a few taps". That'd be great, but the first screenshot shows how I have to "Speak to FitnessAI". Do I really have to have an ELIZA-style chat, and spell out the muscle groups I want to work out today? This just looks lazy. A pseudo-English command line is a terrible design for this.<p>You have the official "Download on the App Store" badge, but it links to a web form that requests my phone number. That's not an acceptable use of Apple's badge, according to their rules on the webpage you downloaded it from.<p>Using algorithms to optimize my workouts sounds like a good idea in principle, but I see no proof that it works as advertised, and everything else about this app is mildly distasteful.
Even for a single exercise, there are a lot of different variables: weight, number of sets, number of reps, recovery time between sets, recovery time between workouts, etc. Were all of these variables adjusted and taken into account or were some of them held constant?
Their blog post says not to rest for more than 90 seconds between sets. I can see why the app would work better with tight groupings but 90s is not enough max gains and recovery, especially for beginners.
I think this will not work unless things like individual training experience, proper form execution and diet are taken into account.<p>I also think that people are pretty stupid and you will earn a lot of money from it.
This seems targeted at bodybuilding (at least the landing page screenshots are). If this really works, it would be interesting to see how the algorithm fares in competitive sports like olympic weightlifting and triathlon.
my 2c: The default value for "weight" in onboarding seems to be 120kg. I'm pretty sure you can set it to 75kg[1] to avoid a lot of scrolling in the onboarding.<p>However good job !<p>[1] average: <a href="https://en.wikipedia.org/wiki/Human_body_weight" rel="nofollow">https://en.wikipedia.org/wiki/Human_body_weight</a>
