fibers (the ones that contract during high - intensity moves and help improve muscle tone) Sit with knees bent and feet
on floor.
By focusing
on the lowering part of the movement, you can powerfully overload your muscles and recruit more of their fast -
twitch fibers, which leads to greater stress and greater adaptation.
When performed with light to moderate weight, explosive lifts will activate more fast
twitch fibers in you chest.Explosive lifts will also build strength and power because you only push the weight and you don't use your energy to slow down the bar
on its way down.You can use ballistic bench press for explosive reps.Right after your regular bench press set, go to the smith machine and do 5 - 6 ballistic reps.You should use around 50 - 60 % lighter weight for the explosive reps.

twitch muscle
fibers!

on the bar, the brain de-recruited the largest and strongest active fast
twitch fibers, leaving the slow and intermediate active and available to continue working.
All of your slow
twitch fibers will be activated, all or nearly all of your intermediate
fibers will be activated, and some of your fast
twitch fibers will be activated
on that first rep.. The reason all those
fibers are activated
on the first set is that the slow
twitch fibers are not strong enough, by themselves, to lift the weight.
I've increased my curl weight to 100 from 80 in about 3 weeks by mixing up
on / off days and light / medium with heavy training (trying to take advantage of the muscle «continuum» and hitting the
fiber on light weight most
on one but ending with hitting the fast
twitch for heavy
on light medium workouts for at least 1 set of 5 rep)

If you do 10 slow reps (slow
on both the positive and negative portions) with a relatively light weight, say 75 % of your 1RM, then do 10 superfast reps, and finish with 10 normal - speed reps, you can fatigue both the slow - and fast -

In light of your reply to this question, what are your views
on the popular theories of slow and fast

For example,
on a set of squats, the trainer takes a brief rest at the top position as he psyches himself for the next rep..

All of this means that when you challenge your body to do more WORK — for instance, by going very slowly
on the eccentric portion of the movement — you get more of your important type 2 (fast
twitch) muscle
fibers involved... which means you become more metabolically active to burn fat... AND build greater strength.
