Most of the time, in most workouts; the diet is the key. But....
is weight loss your goal or do you want or need to add more strength training into this?
Let's see - here's the Coles noted version of a workout that worked for me.
-eat 6 to 8 small meals per day -carb light towards the end of the day.
-nothing white -no white bread, no pasta, no potatoes, no white rice - substitute with brown or if you can cut it out add anything green.
-hold the supplements for now.
-morning workouts - cardio to start (20 minutes), weights then end with cardio (30-60 minutes)
-for weights -the workout is super easy ...3 days of weights -cardio everyday is you want (the more you do the more you lose)
-weights...day 1 - olympic bar squats, lunges with dumbells, hack squat or leg press...day 2 - olympic bar deadlifts, reverse grip barbell rows, lat pulldowns or chins...day 3 - bench press, incline dumbell press, dips. All first movements to be done to your 2-3 rep max (if it can be done safely). Don't worry about your arms or shoulders -these movements will take care of those parts.
- for supplements : a good multivitamin, vitamin C and E, glucosamine, for protein products go low calorie (Designer Protein is good for this) -twice a day. Creatine tends to add water weight -the gains tend to go if you come off of it. Creatine will help if you decide to push heavy weights later on.
- if you want to cheat -ephedrine based supplements will help -watch your blood pressure though.
Good Luck
