Hi, I'm doing some really basic weights because I've read it helps with weight loss and also I don't mind the look of gaining a bit of muscle in the upper body and arms but don't really want to bulk up big time. I just do a few basic excercises, pushups, situps, bicep curls, pull ups, lifting above the head, back extensions and a few other excercises I can make up with a couple of dumbells. The reps range from 20 to 5 depending and I just kinda do it till I feel I've had enough. My question is, is it important to have rest days in between workouts? Sometimes I'm sore and take a rest day or two or skip the excercise if its still really hurting from the last time. But lately I've found I'm not really getting sore and could work out every day. Is this a bad thing? If I don't take a breaks am I limiting the effectiveness of my workouts even though I feel great? Also, I do a cardio workout most days, does this factor into it at all? Thanks in advance for any advice.
