Charles Glass’ Ab Workout
Glass shared a video where he discussed a four-exercise workout to improve your midsection:
- Seated Crunches – 4 sets, 8-12 reps
- Standing Rope Crunches – 4 sets, 8-12 reps
- Leg Raises – 4 sets, 8-12 reps
- Seated Oblique Twists – 4 sets, 8-12 reps
Seated Crunches
The workout began with what Glass pegged as his favorite ab workout of all-time. He discussed the importance of maintaining pressure by lifting up.
“My favorite all-time is just to sit and crunch. You can feel the pressure as you crunch down, you lift up, so everything is crunching up. You’re lifting the hips.”
Standing Rope Crunches
The standing rope crunch brings the most benefit by squeezing at the bottom of the rep once you bent at the waist.
“Squeeze at the bottom for maximum contraction then slowly return to the starting position. Keep the movement controlled and focus on using your abs to power the crunch.”
Leg Raises
Leg raises is a classic move that targets the lower abs. Charles Glass advised to let your lower half burst off the pad to make sure you are getting the full contraction.
“Engage your core and focus on bringing your knees toward your face while lifting your torso. Make sure your glutes come off the pad as you crunch, fully engaging the abs at the top. Control the movement and avoid swinging.”
Seated Oblique Twists
The final exercise in the workout is the seated oblique twist. Glass always leaned forward to make the exercise more difficult.
“What I like to do is just a regular twist but with a wide stance that stabilizes my hips so they don’t move. The only thing that moves is my torso and it moves quick.”
