Weighted Sissy Squat
Weighted Sissy Squat Exercise Description
The weighted sissy squat is a quad‑focused knee‑extension movement done with the hips held in extension and the torso leaning back as one rigid line. It targets the quadriceps (vastus lateralis, medialis, intermedius, and rectus femoris) while the core braces isometrically to maintain neutral spine. The ankle plantarflexors assist by supporting heel elevation, and the glutes act primarily to keep the hips extended rather than drive the motion. Allowing the knees to travel forward increases knee flexion demand on the quads while minimizing hip hinging. This variation is typically performed holding a plate or dumbbell at the chest for counterbalance, or using a sissy‑squat bench or heel wedge for stability. It suits lifters with solid balance and control who can maintain knee‑to‑toe alignment through a comfortable, pain‑free range of motion.

How To Do The Weighted Sissy Squat Exercise
‘- Stand tall with feet hip‑ to shoulder‑width and toes slightly out.
– Elevate heels on a stable wedge/board (or rise onto the balls of your feet). Hold a plate or dumbbell tight to the chest.
– Brace the core; set ribs down; keep a neutral spine. Gently squeeze glutes to keep hips extended.
– Initiate by driving the knees forward over the toes while leaning the torso back as one straight line from knees to shoulders.
– Keep pressure centered over the mid‑forefoot; do not let the heels drop abruptly.
– Track knees in line with the second–third toes; avoid knee collapse inward or outward.
– Descend in control to a depth you can maintain without pain, commonly around 90° of knee flexion or less if needed.
– Pause briefly while staying braced; neck neutral, eyes forward.
– Rise by extending the knees and “pushing the floor away,” maintaining hip extension and the torso’s backward lean—avoid hinging at the hips.
– Move smoothly; prioritize balance and alignment over depth or load.
– If needed, use a sturdy support (post/strap) lightly for balance and reduce range or weight to maintain perfect control.
– Breathe: inhale on the way down, exhale on the way up.
Weighted Sissy Squat Tips
‘- Keep your torso and hips in one straight line from knees to shoulders as you lean back.
– Gently squeeze your glutes to maintain hip extension rather than hinging at the hips.
– Elevate your heels or stay on the balls of your feet so your heels don’t drop abruptly.
– Drive your knees forward over your toes to initiate the movement instead of sitting your hips back.
– Keep pressure centered over the mid‑forefoot throughout the rep.
– Track your knees in line with your second–third toes to avoid them collapsing inward or outward.
– Brace your core, set your ribs down, and maintain a neutral spine the whole time.
– Descend only to a depth you can control without pain, often around 90° of knee flexion or less.
– Pause briefly at the bottom while staying braced, with your neck neutral and eyes forward.
– Use a light hand on a sturdy support and reduce range or weight if you struggle to maintain balance and alignment.
Weighted Sissy Squat Beginner Introduction
The weighted sissy squat is a specialized lower‑body exercise that emphasizes the front of the thighs while challenging balance and body control. During this movement, the body tilts backward in a straight line from knees to shoulders while the knees bend deeply, so the thighs handle most of the work instead of the hips. The stomach muscles and lower back brace to hold a strong, steady posture, while the glutes mainly support the hip position rather than powering the lift. The calves contribute by supporting the elevated heel position described in the full technique.
This variation often uses a weight plate or dumbbell held at the chest as a counterbalance, and many lifters rely on a dedicated sissy‑squat station or a raised surface under the heels for extra security. Because the knees travel forward and the motion places the body in a leaned‑back position, the exercise suits lifters who already have reliable coordination, stable ankles, and comfort controlling knee movement through a range that feels good.
