What is a Giant Set?
Like supersets and trisets, giant sets are based on exercises done one after the other, without rest.
In this case, the only difference between supersets and trisets is that in giant sets you do 4 or more exercises in a row.
Example
Giant Set
Flat Bench Press - 4 sets x 8 reps
Openings - 4 sets x 8 reps
Funds – 4 sets x 8 reps
Push-ups – 4 sets x 8 reps
You start with 8 bench press reps, move immediately to the openings and perform 8 reps, then do 8 bottom reps and end with 8 reps of push-ups.
All of this is done in a row, with no rest between each exercise, resting only at the end of the push-ups.
This is an example of a giant set.
