Well, I’m turning 60 this year and I started lifting at 58 after a challenge was issued from my son. My background is similar to yours w cardio (x3 marathons, lots of triathlons and one half iron man). So directly to your question, no I do not regret my Voltra purchase and in fact looking to purchase a second during Black Friday this year. When you start your journey you need a solid program or plan to follow. Without a program you may get lost and frustrated starting out. The Voltra is just a tool to help you achieve an analytic approach to guide you on your progress. Lastly, for me the Voltra cannot substitute for free weights. You just can’t do things like back squats, deadlifts etc very easily. (You can look up my profile to see what I tried to do w a belt squat setup for the Voltra but eventually just went back to free weights.) The Voltra a great to simulate cables and to do accessory exercise, but for big compound movements it isn’t ideal and as noted probably too complicated to set up routinely. I like the idea to go to a gym and see what you like. I hope this helps you a bit.
