My husband and I joined a fitness club earlier this year to supplement our cycling. I wanted to do some serious weight training to balance the hours we sometimes spend on the bike --- a few sets with 3# weights at home weren't really doing the trick. I'm 54 years old and in pretty good shape for my age, not needing to lose any weight.

So I signed up for 12 sessions with a trainer. He's taught me about 30 different routines I can do for total-body strengthening. Every other week, he increases the weight just a little on some of the machines. I am now pressing 205 lbs. on the leg press(!!!) and feel a significant difference in my strength on the bike.

However, I am also noticing that my jeans are fitting tighter. I don't think I am eating too much; I may be eating a little more more than before, but I am also working out longer and harder at the gym. If anything, I may be sitting more during the day (I work at a very sedentary job) and don't get up as often to walk during the day. I also eat later at night since we often don't get home from the gym until after 7:00, then eat a light dinner (soup w/ 1 piece of bread without butter) and finish eating about 8:00.

My husband says the added bulk is due to my workouts at the gym (including leg presses, lunges, squats, etc.), but I think I should also be losing fat which would offset the bulk.

Is it possible for my legs to increase in bulk in just a few months assuming everything else has stayed the same? I want to be strong, but not bulky!
