Hi-Lo Bound combines the "old fashioned" high impact aerobic exercises from the 70's and 80's, and a modern rebounder to give you a unique cardiovascular workout. It is well documented the fabulous results derived from the high intensity workout of high impact aerobics, but also the very negative effects of the shock applied to the joints, muscles, and bones. This workout eliminates the shock while maintaining the benefits. Allison Nolan teaches vinyasa flow yoga and is certified by ACE.
