Here, personal trainer Jason Williams, NASM-CPT, gives us the lowdown on the benefits and downsides of both so you can figure out which one is best for you. On top of that, it’s important to note your level of fitness and any injuries you might have. Crunches are probably “easier” form-wise, so that’s something to consider if your back or neck is an issue. Williams himself notes he likes to switch it up. At the end of the day, you can certainly try both to get a feel for which is better to you. Whichever you choose to incorporate into your next core workout, crunches and situps are both welcome additions with plenty of benefits.
