I do German volume training and I get nice results from it.
What I like most about it, is that it has kind of a self-regulating mechanism to find your optimum Time-under-load. The first sets done at 60 % of 1 RM are relatively ez, but you take only 1 minute rest, only allowing partial recovery hence each set slightly more white fiber motorunits are recruited.
Charles Poliquin , who "re-discovered" GVT says that one of the keys using GVT is REPTEMPO: 3-0-2-0 for the short range like barbell curls and 4-0-2-0 for squats
I found out myself that for really short stroke muscles like traps , wrist and abs a topcontraction of 3 seconds works even better... 1-0-1-3
Actually I don't allow 7 between training again but 4-5 days (depends on how I feel)
Sometimes I do even more volume, like hamstrings:
10 * 10 stldl (hitting hams from the glutes)
10 * 10 leg curl (hitting hams from the kness)
or back:
10 * 10 medium grip pulldown (emphasize width)
10 * 10 T-bar row (emphasize thickness)
For smaller musclegroups i adhere to the orignal GVT routine:
Triceps
10 * 10 skull crusher
12-10-8 weigted dip
or something like that.....
Mind that the first sets are kind of enhanced warmup sets... People that tell you not to do such high volume, often disregard their own warmup sets and only count their worksets.
