I weighed around 270-275 during football season for 4 years in college. Off season I would drop to around 250. A normal weight for me would be around 235-240 at 6'2, still is now since high school. Had to keep near the football weight year round.
Only difference I made was watching my carb intake, to either gain or lose weight. I trained heavy (squats, power cleans & jerks, squat cleans, etc) pretty much the same way. One main difference was that I used interval training for stamina, favoring the Tabata protocol. Low carbs & interval training seem to melt the fat off and keep the muscle mass very well. Tabata ( as one example of interval training) requires 20 seconds of intense effort, followed by a 10 second paus and than back to the 20 effort again, pause 10 seconds, etc. Usually anywhere from 5 to 8 cycles are used.
I still suggest to most people, men & women, to maintain their carb intake to 100 grams daily. Which may includes avoiding most grains/bread/pasta. After 3 to 4 week a couple of carb days (usually weekends) can be allowed. Using common sense in the process. If 100 grams don't seem to work fast enough for your body type, than drop to 60 grams or 40 grams at the most.
Lower than 40 grams, for some folks, can have a negative affect on the normal function of the body. Gluten diets also appear to work well, where fat loss is concerned.
Walking (power walking usually) is very effective, but start off slowly at first. If having sand, uneven trails or hills around your area, that that might be first choice. Treadmills are good, with the adjustable inclines. And a lot have TV screens in some gyms. Reading, or audio books, are used by many . Good Luck
