Maybe an odd question, but any ideas for cardio at home (inside) that doesn't involve a large machine like a treadmill or eliptical? I just don't have the space for something like that.
I feel like I'm lacking cardio overall, and I know I will not stick to a running program (tried it about 4 times and always just stopped at some point). I'm also in a position where I know I can't make a gym membership work due to my work schedule, so I've ruled that out.
I keep seeing ads for the TRX system. Is it worth it? It seems more strength training, but if it gets the heart rate up, I'd be into that too.
Any suggestions would be great.
