I didn't touch upon the tri-set in the previous posts.
IMO, a tri-set are 3 exercises, with the designed intention to "attempt" to hit the focus muscle--"from multiple angles"--that a traditional one dimensional/one exercise can not. The theory here is that it "can" recruit more muscle fibers and from different angles than the traditional one exercise approach.
For example:
The Squat, Leg Press, and Leg extension. All three work the same or simular groups of muscles, but are performed differently and from different execution positions.
And, another example:
Chinup varieties, Front Lat Pull-Down (or its varities), and T-Bar Row. Or one could put in the Bent arm/straight arm pull over and replace one of the aforementioned three (I listed the muscle groups it tends to recuit at the bottom of this post)
These could be peformed with reduced or modified rest or no rest (and likewise increase heart rate when performing)
Example:
One performs a non-weighted pull-up for 10 reps. Without resting moves on to the Lat pull down (weight is adjusted to allow for the target rep range), and then moves on to the T-Bar Row (likewise weight is adjusted for targeted rep range), after this one could rest one minute (of a 3 minute rest), and then knock off
Some DB Skull Crushers (just added to show how flexible one can be), and then rest the remaining rest time. Repeat the process.
This "can be" used to break plateaus, and for some, change the routine to be more interesting to prevent being bored.
Brief synopsis.
===================================================
The pull-over (dependent on the hand width), and position of the arm (bent, straight, etc), can put variable amount of stress on the chest (pecs, and other muscles of the upper body).
Here is a short list of muscles that the pull-over "can" recruit, dependent on how its performed:
1. Latissimus dorsi
2. Pectorals
3. Triceps (to a small degree)
4. Teres major (in front of the lat, side of rib cage)
5. Deltoids
6. Rhomboids
7. Levator
8. Obliques
9. Intercostals
10. And causes a good body stretch.
It works more than the back.
Best wishes to all,
And, everyone ROCK ON! Be proud of what you are doing!
