another question on strength

[Guest guest]

if i want to continue building strength on the bullworker should i

keep doing the same thing over and over again (2 X 10 reps followed by

10 second hold on last rep) or should i vary it (1 week do all

excercises isometrically, 2nd week do all excercises 2 X 10 reps

followed by 10 second hold... etc etc)? any suggestions would be

helpful please
