Hey. Thanks! Glad to hear you like the program.
When it says seconds in the reps it's because its a static exercise you need to hold for some time. So you hold it 4 times of 4 times 4 seconds.
Example. You begin: Hold it for 4 sec, go down for 2 sec. You do that 4 times in a row and thats one set. Then you do that 4 times more :) Hope that could help.
