Focus On Your Core Strength
Your core strength plays an important role in helping you generate more power when hitting a softball. Strengthening your core muscles helps optimize body movement when swinging, resulting in increased distance on each hit. Adding core strengthening exercises such as planks and squats into your regular training regimen can help improve your overall performance at the plate. 
WEIGHTED CRUNCH
We know, we know. The dude in the photo isn’t doing weighted crunches. That’s because a weighted crunch is a goal you’ll work up to as you build strength in your abdominals.
“Do bodyweight crunches until you can do 15 reps for three sets, and then begin to add weight for sets of 8 to 10,” Stoppani says.
How To Do It
• Lay on your back with your knees bent at 90 degrees and your feet on the floor
• Hold the weight at arm’s length above your head
• Using your abs, raise only your upper back off the ground (don’t do a full sit-up) keeping it as flat as possible
• Perform 15 reps (without weight) for three sets; perform 8 to 10 reps for three sets if using weight
