All through high school football, now my bjj classes and countless mens health mags ive been told that running is great (duh), but jumping rope is way more effective. Example, ive been told that jumping rope for 5 mins = jogging 25-30mins. Anyone heard this. I am biased because i hate running, way too boring. But have actually found that several minutes of jumping rope isgetting my heart rate up quick and gives me that burning feeling in my chest, which is good. Thoughts?
