I do cardio 3-4 times a week, and I lift 4 times a week. Is there a limit to the number of days between workouts and/or cardio sessions that I should have. For instance, if I run Monday, Tuesday, and Saturday, is the 3 day break too much? Would 3 days be too much without working out also? Right now I have the weekend off (Lift mon, tues, thurs, fri) if I everything goes correctly and I chose not to run on Saturday, provided I didn't miss anything during the week. I just want to make sure that 2-3 days without cardio and/or lifting isn't too much rest?
