Hit your abs in a new way by doing these upper body movements at the halfway point of a sit-up. Maintaining this position while performing any movement with the arms will challenge the abs, hip flexors, and even the neck musculature.
Anchor your feet under something stable and lean back until you feel your abs turn on. Try to keep your spine and neck as neutral as possible. You can go light and do each exercise for 60 seconds, or use heavier weights and shoot for 10-15 reps.
Half Sit-Up Press
Half Sit-Up Flye
Heavier weight can be used with the press and the flye, which requires the midsection to act as an anchor for the arms to produce movement from.
Half Sit-Up Overhead Front Raise
Half Sit-Up Overhead Press
The overhead front raise and press don't allow for as much weight to be used. Instead, the midsection is challenged by needing to support the longer lever created as the load is raised or pressed overhead.
