Beta tested the app and have seen it go through updates, etc. I love the concept and am looking forward to seeing it become a big success. It’s great to have a personal trainer to chat with during the workout and beforehand to plan. To not have to think about planning my own workouts reduces the stress associated with gym time for me. I can always add on an exercise or take it away if need be and my trainer and I plan around my physical therapy. The exercises are well represented in the videos and the app tells you about which muscle groups you’re working, gives you tips on doing them right, and calculates your one rep maxes dynamically. The extra push to go to the gym from someone texting me and giving me a workout plan is just what I need to stay accountable. Looking forward to competing virtually! Oh and the statistics are fun.

Changed my view on working out

So I’m someone who really likes the idea of working out and getting healthy, but when it comes to actually doing that, I fail. I would always tell myself that if I could just afford a personal trainer I would be able to get strong, but the prices were absurd and not something I could afford.

But since Delta Trainer I’ve worked out for 3 weeks consistently, my boyfriend and I have already noticed my legs and arms becoming stronger, and I have a ton of energy. Nates been awesome adjusting to what I can, and willing to push me a little harder to really help me burn calories. I say, if you’re hesitant, try the 2 week trial, you’ll love it!

Amazing Fitness Pal

This app has become the route to a turning point in my life that I never saw attainable beforehand; having the access to trainers in a non-gym environment allowed me to stretch my confidence levels that I wouldn’t see at a brick and mortar location. Additionally, the Apple Watch is a fantastic and incentivizing tool that I not only use during my workouts, but also at work; it’s a great way to remember that I’m paying towards health, not just the latest tech! I hope they continue to scale their programs to reach a larger audience, as I think this is truly the new personal trainer, and a comfortable way to either get back in track or keep on the one you may already have.
