I'm slowly losing weight and incorporating exercise alonside - (5'6 and 11st 9lb). Currently I do cardio - bike/row/stepper/treadmill and 20 minutes of weights, 3 times a week. I've also started swimming and walk regularly. My legs are strong - I can lift about 55/60kg with leg machines (not really sure if that's alot ), but they are fat/big - my thighs are 26 inches. Should I stop with the weights and do something else?
