it all really doesnt matter what you do, unless you have a propper dieet...
dont trust the computers on those things, they dont know your bodyfat % and all that stuff (unless its like a super expensive fitness one, but i doubt someone buys that for home use)
Look at your heart rate, try to work between 120 and 150, here you will burn the most fat.
If you plan is like mine, lose fat and gain muscles, then dont step on the balance every day, because it doesnt matter how much you weight, you can gain weight but still get slimmer (loose fat gain muscles)
calculate your body fat % this is the most important thing to consider.
AND USE A PROPER DIET !!!
a easy & healty day meal (and this isnt a "pro" dieet or whatever, its just a good simple one)
morning : 3 roasted eggs (use olive oil) 4 slices of brown bread, 2 with 2 slices of turkey whites, 2 with 2 slices of chicken whites.
middag : 4 slices of brown bread, 2 with 2 slices of turkey whites, 2 with 2 slices of chicken whites. all of them mixed with tuna
evening : either chicken turkey of fish, together with rice or some pasta (watch te amount of pasta) and some vegetables.
drink A LOT of watter, like 2l a day, dont drink soda & cola, if you want to drink them drink ZERO or LIGHT
^ this is only a start, because if you start working out, you will be in need of way more proteins, try getting whey shakes, its just a pure form of proteins, drink them in the morning and before you start your workout.
btw a workout only has to last like 30min, you can train at home if you invest like $200 you can get everything you need, a barbell with some weights, some dumbbells, a bench and a squat reck will get you verry far.
In my experience as a beginner, try to workout every muscle group only once a week to not over do it (like i said, its an adviser for BEGINNERS)
mon : chest & tricpes
tue : rest
wed : shoulders and legs
thu : cardio (switch it, swimming, biking, running, elliptical etc etc)
fri : back, biceps & forearm
saturday : rest
sunday: cardio & abs (abs only about 10min)
again, this is just a simple beginners program, there are a lot of better ones out there, but as a beginner its nice to know where te start.
