There are good reasons for cardio-intensive guys to move to a better mix of endurance/strength/flexibility in the fitness mix.
Overtraining on cardio – especially without super-disciplined rest and nutrition regimes – can wear down your body, contribute to muscle loss, and allow development of imbalances that make you more prone to injury.
Also, in our time-challenged lives, too much cardio usually implies too little strength and flexibility training. And maintaining muscle tone and staying limber are huge parts of looking and feeling our best, and maximizing longevity, as we move through life’s second half.
And one big concern about reducing cardio – gaining weight/fat – may be misplaced. Evidence is emerging that strength training (with at least a somewhat-intense cadence) burns fat as well as, or better than, cardio.
With these things in mind (but still needing to overcome a “cardio reduction paranoia” mental hurdle), here’s what I changed and what I learned.
