SENTENCING
If your main goal is muscle size, most of your training should be done
using a lifting speed equal to or greater than one using a lifting speed equal to or greater than one second up. Anywhere second up. Anywhere
from one to two seconds up is about right. Any slowfrom one to two seconds up is about right. Any slower than that and you er than that and you

Although it is true that
rapid-force development
and muscle power are
more specifically
stimulated by higher rep
speed, a recent review
of studies comparing
fast (less than one
second up) versus slow
rep speed (more than
one second up) that also
included muscle scans
to measure changes in
muscle hypertrophy
showed that slower
rep speeds may improve
gains in muscle size
by nearly 50%
compared with faster
rep speeds.
VERDICT
For the best gains
in muscle size,
slower repetition
speeds come out
on top.
