Advanced sit up variations to target different parts of the abdominals and hip flexors. These sit ups are hard but amazingly effective!
Sit ups tend to be both overrated and underrated: some people never do them, whereas some people do nothing but sit ups for their core.
The truth is always in the middle. Sit up is an EXCELLENT exercise, but it alone won't maximize your core development. Treat it as a part of your workout and you will get the best results.
One less known aspect of the sit up is that it's not just an exercise for abdominals. Sit up is also a fantastic exercise to target the muscles that flex the hip (hip flexors).
When targeting the hip flexors, the sit up form is just very different because you are purely focusing on hip flexion and not abdominals.
Here are great advanced variations of the sit up to target different parts of the abs (upper and lower fibers) and different hip flexors (inner and outer).
Sit up workout can consist of total of 10 sets of different sit ups between 5-15 repetitions each. In the beginning it's crucial to just master the basic sit up where both hip flexors and abdominals are working hard. These are for advanced only!
