I decided to put two questions I've had together. They are not necessarily connected.
First, about eccentrics. I will sometimes do 2-3 eccentrics (normal speed of decent) into my training. Is it a waste of effort to do an eccentric single at 105-110% as the LAST set on an exercise, without any concentrics following? I was thinking about using a 5-4-3-2-1-N approach and using the negative at the end. The other option was to go N-1-2-3-4-5, but then I have to ramp all the way up to the negative before working down. Do either of these approaches have merit?
Second, what is the basic approach to training when trying to cut around 500 cals a day? Would you stick with lower reps and count on the calories to reduce bodyfat, or would you train in a specific way to burn more fat? Basically the question is higher volume/reps or lower volume/reps when cutting calories?
