We discuss why we think resistance training is a must. Depending on the goal cardio may be more effective initially but resistance has too many benefits long term making it our #1 recommendation if we had to choose one vs the other. Of course, a combo of both make for the best long term benefits, longevity, health, etc but when it comes to doing one vs the other resistance training is king long term for maintaining muscle mass, increasing growth hormone, lean and tone looks, etc.
