Among abs exercises, the Side Lying Leg Lift Left stands out as a squat movement performed with bodyweight. The working muscles contribute to the movement, which is what makes this movement valuable for overall performance in this pattern. What separates this variation from other abs work is that it is performed from a lying position and emphasising a lateral movement path — a detail that changes which fibres take the load and how much stability the movement demands. The 'Side Lying Leg Lift' designation is not cosmetic — it tells you the specific setup and line of pull that separates this from its close relatives. Support comes from the glutes, hamstrings, and calves; the glutes in particular help extend and externally rotate the hip, which is why fatigue there often shows up before the abs is fully worked. Training this with bodyweight needs no equipment at all and can be done virtually anywhere, though it is harder to load progressively once you outgrow it. In a training week, this fits naturally into any session where abs is the priority. The pattern is accessible enough to learn in a single session, which makes it a sound entry point before progressing to heavier or more complex variations.
The Side Lying Leg Lift Left is primarily a legs exercise, but it is never only the legs doing the work.
The general rule for the Side Lying Leg Lift Left is simple: inhale and brace at the top, exhale through the ascent. For heavier sets, take a breath in at the start position, brace as though bracing for a punch, and hold that pressure through the hardest part of the rep before exhaling. Consistent breathing is what keeps your brace intact from the first rep to the last.
Perform the movement slowly with a light load until the pattern feels automatic. Film one set of the Side Lying Leg Lift Left from the side; it's the fastest way to spot what to fix.
Add load in small increments while holding the same tempo and range you established. Track your Side Lying Leg Lift Left numbers so you can see whether the abs is actually progressing.
Progress to a heavier variation of the same pattern once technique is stable at your current load. Small, tracked increases on the Side Lying Leg Lift Left beat occasional maximal efforts.
The Side Lying Leg Lift Left suits most healthy trainees, but it is not appropriate for everyone.
This is general educational information, not medical advice. If you are managing an injury or medical condition, check with a qualified professional before adding this exercise to your programme.
It primarily trains the legs, with the glutes, hamstrings, and calves assisting. The pattern is classified as squat, so the quadriceps, glutes and trunk stabilisers share the workload.
Yes. It is rated beginner-level, and the pattern can usually be learned in a single session with light resistance.
A practical starting point is 3 sets of 6-8, resting 2-3 min between sets, roughly 2x per week. Adjust from there based on how you recover.
You need bodyweight. This needs no equipment at all and can be done virtually anywhere, though it is harder to load progressively once you outgrow it.
As a general rule, inhale and brace at the top, exhale through the ascent. Avoid holding your breath for the entire set.
Knees collapsing inward under fatigue. The simplest correction is to track the knees in line with the toes and keep the mid-foot loaded.
Good substitutes that train the same abs pattern include Ab Wheel Right Out, Crunch (on Bosu Ball), and Barbell Seated Twist. Pick whichever matches the equipment you have available.
Changing the angle changes which fibres of the legs take the most tension, so it complements rather than duplicates your other abs work.
Within abs training, the Side Lying Leg Lift Left is the bodyweight variation to reach for when you want a squat pattern you can repeat consistently.
The core is far more than a visible six-pack. It is a coordinated group of muscles that includes the rectus abdominis — the long muscle that creates the six-pack appearance and flexes the spine — the internal and external obliques on the sides that rotate and bend the torso, and the deep transverse abdominis that wraps around the midsection like a belt to stabilise the spine and protect the lower back.
Effective core training works all of these functions rather than relying on endless crunches. Flexion exercises such as crunches, sit-ups, and hanging leg raises target the rectus abdominis and are excellent for building visible abdominal muscle. Rotational and anti-rotation work such as Russian twists and cable woodchops develops the obliques and the ability to resist twisting forces. Bracing and isometric holds like the plank and its variations train the deep stabilisers that give you a strong, protected midsection during heavy lifts and everyday movement.
Because the core is involved in stabilising almost every compound lift, it already gets significant indirect work from squats, deadlifts, and overhead presses. Direct ab training a few times per week, with a mix of weighted flexion work in the 8 to 15 range and longer isometric holds, is enough for most people to build a strong, defined midsection. Adding resistance to ab exercises over time is just as important as it is for any other muscle.
The most important thing to understand about abs is that visibility is primarily a function of body-fat level, not the number of crunches you do. You can build thick, strong abdominal muscles, but they will only show when body fat is low enough, which is achieved through nutrition and overall training rather than spot reduction. There is no exercise that burns fat from the stomach specifically. Focus ab training on building and strengthening the muscles, and rely on a sensible diet and full-body activity to reveal them.
A strong core improves posture, protects the lower back, transfers force between the upper and lower body, and underpins performance in virtually every sport and lift. Train it deliberately using the popular core exercises below.
