Yeah, we'd all like to lose a few kilos (which will happen when we eat in a calorie deficit), but we also need goals a little more specific. - Stronger - More shape/muscle - Fitter/more endurance
I believe a great program for the general population should include ALL of these goals.
For that reason your training should incorporate - High intensity, low reps to build power (1-3 reps); - High intensity with moderate/low reps to help increase strength (4-5 reps); - Moderate intensity, moderate reps to help with building muscle. (6-20 reps); - Moderate/low intensity, moderate/high reps to help increase endurance(Supersets/dropsets/15-30 reps).
Think of it like this: 1 - The more power you build, the heavier you can lift. 2 - The heavier you can lift, the stronger you become. 3 - The stronger you become, the more volume you can lift. 4 - The more volume you continue to lift (progressively), will help build shape and help avoid plateauing.
