Im all over the place when it comes to training but its always with some goal in mind for that phase of my life.
When I hear "functional" i take it as extrapolating to real life stuff or general fitness. Run here, lift that climb this, pull this, carry that..
Some.peiple.may balk, but crossfit is pretty good for this. Also, rucking is fantastic and tests a person depending on how hard you go with it. Sandbag work also awesome. Running or jogging for cardio if joints are able.
And like Goldenrod said, farmer carries. I finish almost every workout with them.
It's a timely post as im spending my time training for mountain search and rescue, so pretty functional.stuff
When I hear cross fit I think injuries and a rehab specialist's dream. I know there are beginner programs for cross fit. I wish I had it in me to do something and not push it (that was not saying you do - not a shot), but I know my personality and the shit some of these guys and gals dp, I don't consider functional, I consider it nuts. As cool as it is to see some of the guys in cross fit hold metal bars that keep your hands a few inches off the groud (the little movable grips), add weight to their body with a dip type belt/chain, and then stand up side down and do shoulder presses - yes it is impressive and interesting to watch, but I think recipe for disaster but I am still impressed. Respectfully, they are in no better condition than the guys who push it on the shoulder press machine and also train their core just like they train their chest.
I am talking about the guys who are training to compete - the stuff they do is nuts but I guess functional in some way if you are joining the cirque du soleil.
I consider a straight press (bench of any kind), any kind of squat (no weight - reps/heavy - low reps), trap bar - sort of a deadlift squat very functional even if with low weight, or your typical deadlift, squat, even RDL's are all functional as who doesn't pick shit up and need back strength, squat down to pick things up, push things away, and some of the most functional training which I don't do enough enough of it is core (including low/middle back) static holds or moving exercises. I consider had strength exercises which I don't see one other person do - about as functional as you can get. Who doesn't need strong hands in a physical job with great endurance which ties in to your forearms. There is a case to say if you do deadlifts, curls, bent rows, etc. you are training hands but most people use straps. Don't care if it waisted time you could put into more mobility, more strength oriented large muscle groups - I will forever train hands/forearms like I train any body-part.
Just another comment - right or wrong.
I watched the vid and have watched vids of guys doing exercises for mobility in their shoulders and all I can think of is receipe for disaster and your going tare something.
When I think of functional I think of being able to pick up uneven weight and move it. In the real world bars and DB's are not perfectly weighted on each side hence first step is strength in your hands to hold it and then lift, press, carry, etc. Also within reason - flexibility will prevent injuries or lessen the length they linger. This may be a very 'minor' perspective of functional, but it is mine.
