@jeremysry: If you get lower back pain from crunches, try these exercises instead for core! Plank side crunch - you’ll really feel this one in your obliques. Plank crunch to drop - aim your knee at your chest! - this will feel like a traditional crunch Awkward Plank - the balancing act here will really fire up your stabilizers High to low plank - The shift in height here challenges your core in multiple directions! I’d start with 2 sets for 10 reps with every exercise. First set to test things out, second set to try and actually get those muscles fired up! If the exercises feel good, go all in and have at it! #abworkout #lowerbackpain #exercisetips
