Just gonna put some things out there from my own opinion. Please feel free to argue (with something constructive) or add too. Hoping this is the best place on the forum for this if not Chris please move to where you think appropriate.
My opinions on which lifts people who do combat sports (my main focus being BJJ/MMA) should focus on for sport specific
Lowerbody strength - I believe the squat or deadlift both play equal role, but I believe only one should be done per week so you can recover. Picking between the two I think depends on your own leverage, I myself prefer squat as I am short and find I am stronger in the squat, more explosive, and can recover better, where as a taller/longer armed person may favour the deadlift
lowerbody accessory - for this I think the zercher squat, glutebridges, rdl’s and lunges , these could be mixed up every other session / training block. Zsquats work the upperback and underhooks, glutebridges obviously will carry over into a good bridge, while single leg work is a must for take downs
upperbody strength - Floorpress , for me I think this is better than the normal bench IMO as its more likely you will be on your back in a combat sport than on a bench! I also find its a little kinder on the shoulders which already take a beating!
upperbody accessories - facepulls for shoulder health. Tonne of backwork, whos ever said their back is too strong? maybe some incline bench because who wants a pigeon chest?
Power - Full clean over high pull, simply because for me with the clean, you either make the lift or you don’t … high pull I find as the weight goes up I cant help but feel like I’m ‘meeting’ the bar shortening the RoM.
Intrested in your thoughts!
