One of my aims is to gain muscle mass to increase fat-burn.
What would be a good way to achieve this?
It should be natural to concentrate on big muscles, but from what I understand legs for example are not so easy to increase, as we use them a lot (While it is easy to increase the arms muscles, but it won't contribute a lot to the total mass).
How important are "core muscles" in terms of body mass? (I have been thinking that Pilates might be good because it gives a relatively small increase in a large mass of muscles?). Upper body in general?
Are there specific exercises that will increase mass quickly because the muscles are used differently?
The aim is to have a quite moderate program, mostly at home, to be just a bit stronger / more musculus than I would otherwise be. I am looking at high gain/pain, preferably with only one set pr exercise.
