one technique you can use is to do 2 things with your training.
1.optimize your nervous system
2.work for hypertrophy.
(im speaking with regards to someone trying to grow or work for strength)
Optimizing Nervous System
this is the part that frustrates most people, myself included. there are many ways to do it. the basic premise is to use a lighter load and challenge balance and coordination. swiss balls, alternating presses, standing on single leg, half foam rolls etc. all of these present an unstable atmosphere with which you go through your basic movements.
example:
alternating dbell presses on a stability ball.
the fact that you will have to lighten the load and concentrate more, and slow down more will build coordination. the idea here is to build more neuromuscular connections.
another example:
single leg squats.
easier said than done. by ensuring proper knee tracking, you build stability in the knees and also in your core stability.
ah, core stability. you have heard me say it and others as well. this is the key for this training. though you are going through exercises for the extremities and challenging the muscle through balance, your core stability is also getting challenged.
heres where i bring it together. NOW we move on to the power/hypertrophy portion. having done this type of stability training for 4-6 weeks, we are now ready to put the stability ball etc away and move on to power.
when working with the unstable platforms we had to concentrate more and your nervous system adapted. how is this going to help here? simple. now we go back to the good old flat bench, regular back squat, tbar rows etc. with a nervous system that is used to an unstable surface how does it respond to being stable again? by being more efficient. thus, more fiber recruitment, stronger pullls, pushes, etc because the body doesnt have to worry about balance.
so we are back on a power program for another 6 weeks or so with newfound stability, able to push more weight because quite frankly the stability factor is gone, now its all muscular adaptation.
the 2 biggest things you want to challenge to ensure avoiding a plateau: Nervous sytem, and muscular system. the nervous system is the wiring to the motor. if you increase the amount of wires working to the motor, you use more of the motor. basic analogy.
hope that helps.
i find that i get so wrapped up in wanting to grow all the time that i neglect periodization. im impatient just as some of you probably are. its possible to throw some of these exercises in for good measure, and im sure it will help but to optimize your nervous system fully, its ideal to go to a full on program for a period of time, and then come back to the power movements. this is a good way to cycle back on the extreme dietary measures that some of us take too. if you are into protein periodization, ie. high protein levels during growth and then throttling back to allow the body to get efficient with it again, this would be ideal for you.
believe it or not, the body gets sloppy with everything. nutrition, nervous system, muscular system etc.
