What exercises does everybody do with Power Rings or their cousin, the EliteFTS Blast Straps? Here are two of my favorites:
Pull-Ups, beginning pronated and ending supinated (or vice versa). Massive bicep builder.
Weighted Push-Ups (loaded using a ‘dipping’ belt), feet elevated on chair for a full-ROM. Really blasts the chest, triceps, and abs/obliques.
