Sit-up form. The sit-up is an abdominal endurance training exercise to strengthen, tighten and tone the abdominal muscles.It is similar to a curl-up (that target the rectus abdominis and also work the external and internal obliques), but sit-ups have a fuller range of motion and condition additional muscles.
Other muscles worked include deltoids, triceps, and forearms. Equipment: dumbbells, cable machine or "pec deck" machine. Major variants: incline ~ (more emphasis on the upper pectorals), decline ~ (more emphasis on the lower pectorals), cable crossover. Cable crossovers; Dips
Abdominal muscles have many important functions, including breathing, coughing, and sneezing, and maintaining posture and speech in a number of species. [4] Other abdominal functions are that it helps "in the function of support, containment of viscera, and help in the process of expiration, defecation, urination, vomiting, and also at the time of childbirth."
With sit-ups, you're lifting your whole torso from the ground which engages your balance-focused muscles like your abs, hip flexors, legs, back, and neck, adds Glazer. Better posture.
The simplest strength training periodization involves keeping a fixed schedule of sets and reps (e.g. 2 sets of 12 reps of bicep curls every 2 days), and steadily increasing the intensity on a weekly basis. This is conceptually a parallel model, as several exercises are done each day and thus multiple muscles are developed simultaneously.
The leg raise is a strength training exercise which targets the iliopsoas (the anterior hip flexors).Because the abdominal muscles are used isometrically to stabilize the body during the motion, leg raises are also often used to strengthen the rectus abdominis muscle and the internal and external oblique muscles.
Dumbbell incline curl: With an adjustable bench positioned at a 45-degree angle, one could perform incline bicep curls with dumbbells. Incline bicep curls are usually performed with lighter weight compare to regular bicep curls, and by sitting on the incline bench, holding the dumbbells close to the body with elbows tucked in, then performing a ...
Research has shown that both sit-ups and crunches are mediocre strength-building exercises and have injured many people. [3] In a crunch, unlike a sit-up, the lower back stays on the floor. This is said to eliminate any involvement by the hip flexors, and make the crunch an effective isolation exercise for the abdominals. [5]
