Just a quick comment on getting a good connection with HR belts. I also have had a hard time maintaining good skin contact with my HR belt. I started using Aloe Vera Gel as a conductor and all my problems vanished. I found clear Aloe Vera Gel at my local pharmacy. Super cheap, doesn’t smell funny, and doesn’t stain your clothes. Especially helpful in the winter time when I tend to sweat a lot less. Hope that helps.
