fitartistsf saidYou ARE working against yourself...
Cut back on the cardio... Cardio does burn up the fat, but then starts to burn muscle, counterproductive to what you want to do... Ever notice a bicycle racer or a distance runner with any appreciable amount of muscle size??? No. They can't gain muscle size, because they burn it off with all that cardio... Cut your cardio to about 3 times a week, for 30 minutes. Just concern yourself with bulking up for a period of time, eat right, supplement if you need to, then after you have gained some size, increase the cardio, adjust your diet, cut back on the amount of weight lifted per rep/increase your reps, increasing your metabolism, which will then be more for fat burning/toning...
Look at their legs.
They don't work their arms at the same rate.
Keep up the cardio, but, switch to 8 to 20 minutes, HIIT, and keep the calories at the same level or bring them up. Study HIIT, and how to go about it.
I had my biggest legs (28 inches at 5'5") when I rode my bike 40 miles a day and trained with weights.
To the OP here: study up on sarcoplasmic vs muscular hypertrophy. The advice quoted here is WRONG.
Cardio, especially HIIT, is an essential part of heart health, and any sports performance regimen.
Bikers of long distance just burn a lot of calories (about 600-800) per hour, or more, and often don't eat enough to support their work load. There's a trade off between being lighter, and being stronger, and able to develop more power. 2/3 of your lean mass is in your legs.
For the OP here: don't walk away from what will advance your performance and your health.
Competing bodybuilders will push down 8500 calories per day, and do cardio, often for a hour each day. They certainly aren't lacking of muscle.
More activity means the need for more calories. It's that very simple.
HIIT has a long list of advantages over steady state cardio. You can study that, too.
