What is a superseries?
A superset (or superset) is when you choose two exercises and do them in a row, with no rest between each one.
They can be exercises for the same muscle or for two different muscles.
Chest press with dumbbells - 5 sets x 8 reps
Openings - 5 sets x 8 reps
In this case, you would start by doing 8 repetitions of chest press with a dumbbell and, as soon as those 8 repetitions were finished, you would immediately move to the openings and do 8 repetitions of this exercise.
Only at the end of the openings would you have a rest period.
In this case it would be a superseries for the same muscle, chest.
Tricep with forehead barbell - 3 sets x 10 repetitions
Curl bicep with barbell - 3 sets x 10 repetitions
In this example, you would start with the forehead bar tricep exercise, perform 10 repetitions, and at the end of these 10 bar forehead tricep repetitions you would immediately move on to the bar curl bicep exercise without rest.
Only after finishing the bicep curl did a series of this superseries end and the beginning of a short rest period.
In this case it would be a superseries for two different and antagonistic muscles, tricep and bicep.
