I know this has been asked before by the suggested Q&A after I typed in the question, but this is a bit different in that after kickboxing/Muay Thai/boxing/sparring I'm very rarely if ever sore but after BJJ (especially when live rolling after instruction is involved) I can hardly move. More often than not while I don't get very many advantageous positions I also don't get tapped very often either. My cardio honestly isn't that great being a bigger fighter (6 foot tall, 250 pounds, but working on reducing body fat percentage) but this is a kind of sore I only feel after doing high intensity interval training. Could it be something I'm doing wrong not being a very good ground fighter or is it just because I'm utilizing all my muscle groups and strength at once? Is there a way besides cold/hot soak, stretching, and fish oil to reduce soreness? Thanks in advance.
Auto-massage is trending as a main way to reduce soreness generated by hard muscle training.
You can do it with your own hands and fingers or by the aid of a foam roller or a tennis ball. I'll recommend you to check this videos.
Enough sleeping (min 7:30 h) and eating should also help. Don't stop trainning hard, just do it smartly.
Hope this helps you Matt!
PS: I'm also a tall guy, and as one I can tell you that in general, if muscle force exercises are done properly we'll exert a little more effort in comparisson to shorter individuals because of length and weight of the body, also with increased gains in muscle growth, keeping everything always in proportion. This is a matter of proportions and physics.
I get sore muscles all the time.
Remember to get enough rest between training. I usually rest for an entire day, making sure I get enough sleep before my next workout.
I have heard before about eating egg whites and drinking whey protein shakes help with muscle repair, but I have yet to try it.
What really helps is a good massage on the sore area before sleep, and the muscle should heal the next day.
