I do TRX! They only let you do it if you're with a trainer or attending a class, so I only make it twice a week. Oh my gosh, it works! My arms have toned up so much. I can wear shirts that I couldn't hardly get on 3 months ago, and I can hold planks and side planks. WOW
Yes, I know what you mean -*feeling* your muscles working. I don't get that from any other workout. My tip is to keep your movements slow and determined. Don't speed up or you risk using momentum, which defeats the purpose. If you do squats, do one legged ones also -- I'm amazed at how different the strength is in each of my legs. And, although I hate it, cardio on the TRX is beneficial, too. We usually do something where you squat down, then jump up as high as you can - maybe 8 times, then drop the straps and do kicks or jumping jacks, and then repeat, repeat, repeat. And, I thought I was good with cardio - I walk an hour several times a week on incline at 3.5mph, but this kicks my butt! In a good way.
I don't have the room to do things at home, but for now TRX is one of my favorite things at the gym. Have fun!
