I go to the gym 3 days a week for cardio and weight training. I don't want to be muscle woman, but I would like a leaner, stronger body.
For the last 3 weeks I have been doing 25 minutes of cardio (brisk walking on the treadmill at 3.2-3.4 mph) and lifting weights for about 40-45 minutes.
My weight routine is this (these are all done on weight machines):
Arms
Bicep Curls: 3 sets of 15, lifting 15 pounds
Tricep Press: 3 sets of 15, lifting 15 pounds
Shoulder Row/Pull: 3 sets of 15, pulling 30 pounds
Legs
Hamstring Curls: 3 sets of 15 with 45 pounds
Seated Squats/Leg Press: 3 sets of 15 lifting 115 pounds
Calf thingy: 3 sets of 15 lifting my body weight plus 15 pounds
Should I be working more muscles? More types of machines? Is there anything to be gained by working the same muscle group on different machines on the same day?
When I'm finished with my current workout my arms and legs feel like jelly, but I am not sore the next day so I'm not overdoing it. I don't want to hurt myself and I thought that someone here would be able to guide me in the right direction.
Thanks!
