These sound fun... Thanks for the info!No problem man.
1.5 cable curls: you do a full rep and then a half rep out of the bottom (stretched position). That counts as one rep.
Barbell: Do ~8 reps with a full range of motion (it doesn't have to be 100% full ROM though). When using a BB, I like to find a good range where tension stays high (you can lose some at the very top and bottom). After the 8 reps, try to do 10 partial reps out of the bottom, curling up about 3-4 inches (¼ rep) from the stretched position.
DB Hammer: Do ~8 reps with a full range of motion, followed by ¼ reps out of the bottom for an additional 8 reps.
