Over the years I have not been able to figure out a way to eliminate this problem, but rather suppress this problem. In my opinion, there are two ways to minimize this consequence of the superset:
- Be more disciplined during a workout
- Superset compatible exercises together to minimize this effect as much as possible
The second solution is the more practical solution. The first exercise of the superset should target the desired muscle group with minimal help from other muscle groups. A lot of these exercises are isolation type exercises, i.e., the range of motion of the exercise only requires the rotation or pivoting about one joint. The second exercise should supplement the first exercise by using other muscles to help workout the target muscle even further. A lot of these exercises are compound type exercises, i.e., the range of motion of the exercise rotates or pivots about more than one joint. Generally, compound type exercises uses more than one muscle group.
To illustrate this, consider one of my all time favorite superset exercise combos: the pec dec fly and the decline barbell press. For the first set of my superset, I would normally perform approximately 6-10 reps for the pec dec fly. For the most part, this exercise targets my chest muscles effectively and I can feel a nice burn towards the end of the set. I would then push my chest muscles even further by immediately performing a set of decline barbell presses, which utilizes my fresh, unused triceps to help my chest muscles.
For now, this solution is sufficient for my workouts and has provided good results. Any thoughts?
