On the Floor, holding onto an object for stability. Leg Raises are a great exercise to challenge the lower abdominals and hip flexor muscles.

Single Leg Raises or Scissor Kicks, is a challenging lower abdominal and hip flexor exercise.

Requiring stabilisation from, the Leg Kickouts provide a difficult abdominal exercise whereby the legs flex into the abs and extend outwards parallel to the floor.

Hip Hikes add a difficult variation to exercise the abdominals and lumbar muscle groups. Leg strictly vertical, the action requires lifting of the pelvis from the floor and lowering with control.

In addition to the leg raise or hip hikes alone, combining these creates a difficult exercise to develop trunk strength.

Straight from the 'Rocky' Film, so it must be good! Also known as a Dragon Flag, this is an advanced and difficult exercise severely challenges the entire trunk eccentrically by controlling the lowering of the legs from an elevated position.

Required stabilisation to keep the upper limb still. This lower limb dissociating exercise challenges trunk rotation and its coordination with the lumbar spine.

The V-Sits are a challenging abdominal exercise which requires full extension of the upper and lower limbs to lengthen the abdominal musculature and full flexion to shorting the abdominal musculature. It also works the lumbopelvic muscle structures to also contract, balance and stabilise the body.

A difficult exercise to control, the barbell rollout challenges trunk and upper limb strength and coordination. It requires adequate strength levels and shoulder mobility to execute to range.

Criticized by many as the 'dangerous' lumbar exercise, the Good Morning with an appropriate load is a fantastic lumbar and upper hamstring eccentric strengthening exercise. Can be modified with a weight hugged anteriorly to begin with.

Full trunk rotation at 90 degrees. With the arms lengthened across the barbell, this exercise is going to increase abdominal torsion with dissociation of the upper limbs. An ab burner and a pec and anterior shoulder stretcher.

Rotary straddle bench twist exercise with increased difficulty by leaning the torso back to 120 whilst straddling the bench or locking feet into DB (as seen in video). In this position fully rotate around the spine to increase strength at range through the anterior slings whilst challenging trunk strength.

A PJLawler Special, the plate dance challenges the trunk immensely by creating rotatory tension of the abdominals between the upper and lower limbs. An ab burner, the upper limb rotates to the opposite of the lower limb. For athletes requiring rotatory force development of the trunk or just a tough active abdominal exercise, this exercise is best done with a plated weight for 10-15s.

A Must Do For All Athletes. The Back Extension on the Roman Chair is a traditional and crucial exercise to learn. DO NOT FLEX the Lumbar Spine, this is a pivoting motion of the Lumbo-Pelvic Complex and Hip joint that develops strength in the Lumbar Spine and Proximal Hamstring muscles.

2 in 1 Exercise. Roman Chair Back Extension with a Reverse Twist.

2 in 1 Exercise. Roman Chair Back Extension into a Front Raise.

2 in 1 Exercise. On the Roman Chair, Back Extension with a Lateral Raise

An obliques and QL tearer! the Roman Chair Lateral Raise is a difficult exercise for the trunk, that requires strength through the lateral trunk to stabilise and complete.

2 in 1 Exercise. On the GHD Machine, Back Extension and Lateral Raise with DB in hand.

2 in 1 Exercise. GHD Back Extension and Front Raise with DB in hands

To add difficulty to a Sit Up or Incline Sit Up, suspend the torso from a bench or GHD.

Increased difficulty to the Russian Twists, by suspending the trunk off a GHD or Bench.

Rotary suspended twist exercises. Moderate to High difficulty by suspending the torso back to 120 whilst locking feet into GHD with a weighted plate or DB in each hand and rotating around the spine.

Combination 2in1 exercise of Suspended Sit Up with DB Fly. It has a moderate to high degree of difficulty. This will strengthen your abdomen thoroughly.

Combination 2 in 1 exercise of Suspended Sit Up with a Single Arm Fly or 'Rip'. It has a moderate to high degree of difficulty. This will strengthen your abdomen thoroughly whilst create tension through the anterior sling to develop force translation through to the upper limb.
