While the exercise you have listed will to some extent. Now the BUTT...none of the movemenst listed above produce anywhere near the same power output as Olympic movements.Note that you don't have to learn the relatively technical Olympic lifts to benefit! You can do explosive work like:
- box jumps
- dumbbell swings
- one-arm versions of the snatch and clean
- push press
All of these are just excuses...a mean of justifying why you don't want to do them....all of which will have you moving fast and hard. I don't do Olympic Lifts (no hands-on instruction, no bumper plates, no safe place to ditch weight, no Olympic bars)
Let break them down. "...no hand-on instruction"...one of the best training video on how to learn and perform Olympic movement Harvey Newton's "Explosive Lifting For Sprots listed on this web site. http://exrx.net/Store/HK/ExplosiveLiftingForSports.html
"...no bumper plates..." Few need bumper plates for such movements as power clean, hi pulls, and power snatches. The weight can be controlled. I never have had any bumper plates or trained with any. I've trained the the Olmpic movements, listed above, since I was a kid.
"...no safe place to ditch weight..." As I stated, that is not a problem with the movements that I've listed above.
The primary need for bumper places and a platform with neatherthal lifter is that dropping the weight make them feel macho.
"...no bar..." Then make an investment in you future by purchasing one.
I am constantly amazed at what people "can't do," when it's really what they chose not to do.
Well, doing something is better than doing nothing. So, the exercise you perform are useful. As you said, "The most important thing, though, is to just do it."but I do the exercises list above. You can get lots of explosive power that way too. I know I have - I've watched my strength and power go up because of doing them.
