@joshuaoguntuase: Similar to biceps. Triceps for the most part are typically over complicated. Doing a compound Tricep move, will often involve a shoulder extension component meaning you’ll be able to bias the long head. You also load more weight with these moves (so win win) . In terms of medial and lateral you’ll work this in any elbow extension movement. Now, to be fair, most don’t even need to worry about biasing each head. Typically training progressively hard with two moves will do.
