Mood swings in relation cardio/weightlifting?

I think I do the same sometimes after lifting. My husband says it makes me mean sometimes. Not really mean, just very irritable and almost like I want to fight

ETA: It may be related to testosterone levels, not sure.

I feel amazing after lifting weights, pumped up, clear and full of test.
Rest days I feel down, especially if I skip my cardio

I used to just be a runner. everytime i went to the gym i would get on the treadmil and do some crunches after no weights. i always felt GREAT after these workouts. When i started personal training i became in the WORST mood after my workouts.. not so much like i wanted to fight with someone, but so exhausted and just plain angry! don't know what it is. I asked my trainer too and he said it had something to do with the lactic acid or something? I dunno.. but you're not alone.

thats one of the great benefits of cardio training. aerobic workouts release endorphins which gives you a " high " for lack a better word. Endorphins make you feel good...its often called the runners high.

EXACTLY how I feel. I want to pick a fight with everyone! By nature I am feisty but weightlifting pushes me over the edge. The testosterone comment makes a lot of sense.

Sometimes I don't feel like that though... I feel great. I think it's however my mood is beforehand, the lifting just sort of intensifies it, you know?

i think its to do with testosterone levels

I have felt exhausted after certain workouts, especially leg day, but never had mood swings....unless I couldnt go. : )

I always eat enough to fuel my workouts. I wonder if you guys are not eating enough. Also rest days are very important with strength training. You could probably get away with cardio everyday of the week but strength training almost requires rest days. I dont mean days where you do cardio instead. I mean do nothing to repair and recover.

Are you guys eating enough fats. They are very important for brain function, hormone balance, vitamin and mineral absorption and all sort of other stuff.


..

I always swim 30 laps after a weight training session, so I guess I don't give my mood a chance to swing.
Swimming is generally the icing on the cake after a hard workout. I wouldn't want to do one without the other.

I've never really experienced any aggressive feelings after a weight training workout, that's probably
predicated on the fact that I always do a full yoga routine for a warm up before I start lifting.

The testosterone things makes sense, as does diet, for some. (Not me, I eat way above MFP's idea of what 'maintenance' is, macros ok

Re the psychological stuff - I like the feeling of lifting - sensing different muscles work against tension, paying attention to balance & form as a kind of challenge (which it is for me, I'm still learning).

But, can't say I enjoy it as as much as other things, where, idk, you have a sense of moving forward in space and time, or getting into a kind of zone via repetition. There's more regular & deeper breathing with some things - swimming, yoga, running - more oxygen. So many people seem to grunt & hold their breath while lifting.

Or with eg calisthenics (or dancing, especially) there's a different kind of aesthetic quality to the things you do - you get into a rhythm, add some variety with some big or explosive movements. Maybe use a bigger range of motion & stretch out your limbs now and then, like animals & kids do, just because it feels nice. Those movements are about spreading out, vs deliberately compacting force within your body.
