Two forethoughts:
1. when Pushing the Prowler the upper body works isometrically (
shown here by Chase and Rip)
2. when you aim to push or lift an immovable object as if your kid's life depends on it (a truck in Park gear?) you aren't doing work from a Physics point of view (because the truck isn't budging), but you sure are doing metabolic work and are out of breath by the end of the bout.
Hypothesis:
Pushing a wall with similar set duration, number of sets
and intensity as one'd do in a Pushing the Prowler HIIT session is likely to result in conditioning improvement
Video examples of the move I am referring to:
Overcoming Isometric Wall Push
Wall sled push
Split-Stance Isometric Wall Push (Overcoming Isometrics)
Move The Wall Isometric Challenge
Any constructive thoughts*?
Thank you.
*"Isometrics do not increase strength or muscle size" will be unhelpful since we're talking only Conditioning here.
