ABS Workout Challenge. HARDEST 4 MIN OF YOUR LIFE
:
A challenging 4-minute abs workout can include exercises like Dragon Flags, Standing Barbell Rollouts, or TRX Oblique Crunches, all known for engaging the core and building strength. The 4-minute workout may also involve exercises like Bicycle Crunches, which a study indicated as one of the best abdominal exercises. The workout might also include exercises that target the lower abs, like Hi/Low Scissor Crosses, which can be challenging but effective.
