<< I have seen several definitions of the Janda crunch, this being the latest
from:

“Find a high bench or something similar. Drape your legs across it like you
normally would. Now, as you crunch up, dig your heels into the bench. What

Anyone who has trained seriously with weights for a while knows that there
are many ways of executing full back squats with different types of
apparatus. Here are a few of them:

2. Free weights plus elastic bands (increasing resistance)
3. Free weights plus chains (increasing resistance)
4. Free weights plus partner adding resistance (increasing resistance)
5. Squats on Smith machine
6. Squats on isokinetic machine (accommodating resistance)
7. Squats on cam machine (varying resistance)
8. Free weights plus isokinetic resistance
9. Squats with weights hanging off belt

Each one of these different apparatus types of squat has its own
applications. Would anyone care to comment on some of them with which they
may be familiar? What are the specific values of each of these types of
squat?
