interval training is the best way of improving fitness. I have noticed a huge improvement since changing my gym routine.
also i concentrate more on weights than the traditionally accepted "cardio to burn fat" regime.
I still do cardio but its based on intervals, and i use a 32kg kettle bell for interval/weights mixed. that is the best workout i have ever had
Quite right, too.
All that truly matters, in terms of getting leaner, is balance of expenditure, really. And for those that want to retain LBM, rather than just achieve weight loss, you're much more likely to get leaner by expending more than you take in, and by encouraging your body to retain LBM / muscle, as opposed to some naive or outdated concept of where you perceive is a good way to fuel exercise.
I've said it countless times before, but often it falls on deaf ears, doing SS cardio is largely good for improving at SS cardio (until the improvements largely plateau, then it's just some
expenditure) - that may well be a worthy goal - as may training at specific heart-rate zones - for other athletic, or sustainable reasons.
But those that prefer things like kettle bell workouts, or lifting weights, often underestimate the impacts on the cardiovascular system, and some are under the belief that only traditional cardio regimes really improve that.
For probably many, the most important thing (assuming a given of safety) is a regime they find challenging, yet sustainable - whether that be intervals, steady state, or some other kind of exercise routine that also impacts the cardiovascular system (eg kettle bell routines, boxing training, spin sessions, lifting weights...). Some people like moderate intensity, sustained, some people like intervals or higher intensity, but briefer workouts.

Indeed - it's rare, indeed, that there's much new under the sun...
