... decisions about how things should actually work. The project eventually moved into a fully native iOS build using Xcode and SwiftUI. From there it kept growing. A simple workout planner turned into something that can now handle strength and cardio workouts, Apple Watch integration, health and recovery data, hydration, fasting, training trends, and progress insights. And somehow, that project that started as "I wonder if I can build this?" eventually became a real app that passed App Store review ...

... building RAYNOLSE, a smart jump rope we are preparing for a Kickstarter launch on June 30. The product direction is pace-guided cardio: instead of only showing stats after a workout, the rope/app should help people know what pace to hold, how hard to go today, and how to progress without turning jump rope into a complicated fitness setup. I am trying to validate the positioning before we push more paid traffic. Questions I would really appreciate feedback on: Does ... ... pace-guided cardio

... thing gets worked on. One thing ships. It forces you to scope small enough to actually finish, and finishing something every day compounds fast. Once the work block is done, I switch to full workout mode - an hour of cardio minimum. And like Nika mentioned, keeping dumbbells and resistance straps in eyesight is real. I'll grab them between coding sessions just to stay moving. It keeps the energy up and the bones settled for the rest ... ... mental space than actual time. The longer you push it, the heavier it gets. Getting it done first clears everything else. Comment from Susanne Ertl(@susanne_ertl): I ve noticed prioritizing gets tricky when it s not just work vs

... power, grace, and zero saddle pain. Most fitness tech focuses on digital screens. We focused on the human frame . Traditional bikes force weight onto the pelvis and compress the spine. After 30 years of prototyping, we ve launched the Cardio Speeder a machine that turns a "ride" into a "flight." Why it s different: Orbital Mechanics: Upper body bars turn cardio

... Claude code or GPT Copilot extension for VSCode more than Cursor. I don't understand the hype around Cursor, why is it better than just having an extension? Comment from Germ n Merlo(@german_merlo1): I was trying Cursor and VS + Copilot, and the first one is better by far. Starting now to test Claude Comment from Raf Vantongerloo(@rafvantongerloo): @minach  Thanks, I think most vibe coders are using approximately the same tools. :) I've only recently discovered Emergent, they ... ... them "for free" for a year with a Lenny's Newsletter subscription. That's why. Lol Comment from Raf Vantongerloo(@rafvantongerloo): I use @Lovable a lot to create websites, then @Replit to make Chrome Extension, but I use @VS

... base energy cost of chores, and ChoreFit enhances that by factoring in weighted vests and wrist bands, which increases load and energy expenditure. It s the first time this invisible labor has been reframed as a hybrid of cardio + strength training in a validated, trackable way. I m working with freelance developers to bring this to life and we re launching the beta October 10th. I d love your feedback on tracking, calibration, and usability so we can make invisible ...

... everyone I recently launched my first fitness app, called bFitness, and I d love to get your feedback or advice from fellow makers and users here! What it does: Log workouts easily (weights, cardio, yoga you name it!) Syncs with Strava, Google Fit, and soon Garmin Clean UI with progress tracking via simple graphs Privacy-focused & lightweight no ads, no distractions This is a solo-built project that came out of my frustration with clunky, bloated fitness apps ...

... runs like how has my 5K been progressing over time, or sprints. "Compressed" app coming soon... maybe? Comment from Gabe Perez(@gabe): @jakecrump  oh that's super interesting! You're like in theory combining weight training with some cardio. I'm actually surprised there's no way to customize this. Let me do some digging! Comment from Tijs Teulings(@_tijs): I m updating my app Kilowatt to include a new Garage feature that will allow people to add custom ... ... Jaisal Rathee(@jaisalr): @jakecrump  Thanks Jake! Means a lot coming from you. Working on user dashboards + community features Comment from Jaisal Rathee(@jaisalr): Yooo thanks for doing this Jake! I'm building tinystartups.com -- a "tiny" launch platform and alternative

... just need to move. Comment from Nika(@busmark_w_nika): @seanphwang  Just yesterday, a post by him about the topic. I am realising sleep's potential now. Comment from Edward Michaelson(@emikes919): sleep, lifting heavy, and intense cardio are the obvious GOATs, so will set those aside. If I had to choose ONE, it would be prioritizing mobility (through yoga or other methods). Changed the way I feel all the time, physically and mentally. Gave me more power when ... ... Hwang(@seanphwang): @sohamgoswami1  Great combo! Do you have a particular reason you're tracking your macros? Comment from Sean Hwang(@seanphwang): @novie_dizon  Right - sleep is so critical! The difference between the day after getting good sleep vs

... That sounds great! I've definitely run into the issue of getting a recommendation from an AI and it not taking into account the equipment that I have. And yeah, I've gotten the "do 15 minutes of cardio" type of advice for sure. It sounds like what you're describing is ultimately what I know I would love to use, which is an AI fitness product that mostly just gets out of my way and provides some guidance when ... ... with zero setup. You just tell it what you want once, and it adapts from there. One feature I m particularly proud of is how specific and personalized the routines are. No vague "do 15 minutes of cardio

... Comment from Nika(@busmark_w_nika): How precise are all of those health trackers e.g. calorie burners and those apps that reckon approx weight lost? Because even when I do any activity, it doesn't count conditions (hot room vs cold environment which also affects burning calories). Even the ratio of weight lost was it fat, was it water? Comment from David Manda(@davidmanda): @steveb  Hi Steve, thanks for the question. Yes I do! I will focus my answer ... ... focus with Movitalis is. It's also the thing I know the most about and what will move the needle the most, after you get decent sleep and have a balanced diet. The 2 main predictors of longevity are cardio

... very interesting that is similar to your question: a prediction of how long you will be able to sustain various daily activities (such as walking up a few flights of stairs). This prediction changes based on improvements in your cardio capacity and strength, which the app tracks, so you can see how your healthspan increases - just not at the hourly level. Thanks for your question! Comment from David Manda(@davidmanda): @bradharrs glad to hear! I am trying ...
