This is a question that has been much debated over the years and does not come with an easy answer. I can tell you what has worked with my clients over my twenty years of training.
I cater to the general population, which let’s face it, thats most of us. I like to see two days of lifting a week, three to four days of cardio and a sound diet. Let me now elaborate on my three tiered approach.
With weight-lifting or negative resistance training I like full body workouts set up in a push/pull fashion, with a heavy emphasis on functional movements. I also like to focus on corrective movements based on the Functional Movement Screen (http://www.functionalmovement.com/fms) that I give to all my clients.
The cardiovascular approach we take is very low risk. Two days of elliptical and two days of spinning. Both are no impact cardiovascular options which is key to safety and continuance of regular cardiovascular training. Elliptical training should be done at 55-65% of maximal heart rate to help build a strong cardiovascular base. Spinning covers the need for interval training which is essential. See link for good explanation: http://www.sparkpeople.com/blog/blog.asp?post=7_good_reasons_to_try_interval_training.
As far as diet is concerned, we have a very specific approach that combines a detox cleanse and simple to follow five meal a day approach. It is very much based on being able to fit into the busy schedules that everyone seems to have these days. For more details see link: http://jettllc.biz/services/nutrition/.
