Your Questions About Rowing Machines.

How much weight would i loose in a week from free weights and using a rowing machine?

Now i am doing this healthy i aint starving myself to death or anything like that , but i have got a habit of checking the scales every day , which is bad i know because weight lost is easily weight gained.

1 hour a day on the rowing machine
20-30 minutes lifting free weights , 20kg i think.
