Every couple of years a new exercise, program or piece of equipment — that initially looks odd or strange — becomes a new norm for fitness enthusiasts.
Take the foam roller, for example. When the National Academy of Sports Medicine (NASM) explained how it could be an important tool to improve range of motion and movement in the early 2000s, the only people who used them initially were NASM Certified Personal Trainers and their clients. Fast-forward 10 years later, and foam rollers are found in most fitness facilities. Many people use them as a tool in their fitness routines, warm-ups, cool-downs and/or on recovery days.
