you're not out a load of $$ if you end up not finding you don't use it as much.
Hi uppity, that looks like a decent machine exercise wise. I've collected a number of machines over the last several years after I too determined I wanted to get more fit. I also had assumed for a long time that my daily work (outdoors, as a builder) was sufficient for basic activity... and it certainly helped. But active as I was, I was seldom pushing my muscles to new levels of work and certainly wasn't working at aerobic levels for more than brief moments.
Your machine is certainly a low impact one, your joints -especially knees and ankles- will thank you. Both exercises can really get your heart going especially if done in the 'burst' mode of "high impact- interval" (google HIIT or tabata training)
I have a recombant bike/rower that I like a lot. Also an old treadmill, and my two favorites, popular from 'exercise era of the 90s'
a "Health Rider" and a tony little Gazelle strider. Both of which can be found on Craigslist often for around $25.
I like the variety of moving to different machines in my (now a little crowded) basement. However, I always include a bunch of plain old push ups, sit ups, burpbees, chin ups, jumping jacks, etc that involve no machine and therefore no investment.
May I also recommend several books I found helpful: Smart Exercise by longtime fitness guru Covert Bailey, and In Defense of Food by Michael Pollan, and any book detailing the "Mediterranean diet"
Good luck on your 'journey towards health' !
