A leg press, Smith machine squat, front squat or goblet squat can keep knee-and-hip extension work when a hack squat machine is unavailable.
The original supports your back beneath a moving sled. Other setups change torso support, load position and balance, so they do not inherit your hack squat working weight.

These are curated alternatives, chosen for the movement and the job the exercise does in a workout. A shared muscle group is not enough. Read what changes before choosing: support, range of motion, balance and resistance can all differ. If your goal is to improve a specific lift, alternatives do not replace practice of that lift.
For a similar vertical pull, consider assisted pull-ups, pull-ups, chin-ups or a band lat pulldown. Rows can fill a general back-training slot, but change the direction of the pull.
A hack squat keeps a supported machine setup. Goblet squats, front squats and split squats offer options with free weights, while bodyweight squats work without equipment.
Dumbbell bench presses, machine presses, floor presses, push-ups and band presses can fill a horizontal pressing slot. Your equipment and the range of motion you need help decide which fits.
Supported sissy squats and reverse Nordic curls offer bodyweight knee-extension options. A single-leg extension uses the same machine, while a goblet squat can fill a broader quad-training slot.
Seated and standing machines retain resisted knee bending. A stability ball, suspension trainer or fixed Nordic anchor offers other leg-curl setups when no curl machine is available.
Cable and machine lateral raises keep the arm moving out to the side. Choose the setup you can use and compare how its support and resistance differ.
Front squats retain a free-barbell squat. Hack squats and Smith squats offer guided setups, while goblet squats and dumbbell split squats work with different free weights.
A barbell, shoulder press machine, kettlebell or band can provide an overhead-pressing option. Compare the change from the seated dumbbell setup before choosing.
A rope cable curl retains a neutral grip. Dumbbell and EZ bar curls keep elbow-flexion work while changing the hand position.
Barbell, EZ bar, low-cable and band curls offer other ways to load elbow flexion. Compare the grip, shared load and resistance before choosing.
Machine rows, chest-supported dumbbell rows and bench-supported one-arm rows retain horizontal pulling. A band row offers a standing option with a secure chest-height anchor.
Barbell, Smith and incline machine presses retain an inclined pressing setup. A flat dumbbell press can provide broader chest pressing if an incline is unavailable.
Lying extensions, supported dumbbell kickbacks and overhead cable or band extensions keep elbow-extension work when a high-pulley pushdown is unavailable.
Smith calf raises and a leg-press calf press retain nearly straight-knee ankle work. Seated calf raises provide a bent-knee option with a different calf-training emphasis.
Pushdowns, overhead cable or band extensions and supported dumbbell kickbacks offer other ways to load elbow extension when the lying setup is unavailable.
A barbell or chest press machine retains a supported horizontal press. Dumbbell floor presses, push-ups and band presses offer options without a flat bench.
Chest-supported, machine, cable and bench-supported dumbbell rows offer horizontal pulling with different torso support. A band row provides an anchored standing option.
Trap bar, sumo and dumbbell deadlifts retain a floor-to-standing lift. A Romanian deadlift offers a standing hip hinge when broader hip-extension work fits the workout.
Seated dumbbells, a shoulder press machine, a single kettlebell or a band can keep overhead pressing in the workout when a barbell setup is unavailable.
Dumbbells and a Smith machine retain a standing hip hinge. A low-cable pull-through offers a hinge with resistance coming from behind you.
An EZ bar, dumbbells, a low cable or a resistance band can keep standing elbow-flexion work in your session when a straight bar is unavailable.
Incline dumbbell, Smith machine and incline machine presses preserve the incline pressing slot. A flat barbell bench press is a broader option when an incline setup is unavailable.
An assisted pull-up or lat pulldown offers adjustable vertical pulling. Chin-ups change the grip, a band pulldown uses an anchor, and a dumbbell row offers a broader horizontal-pulling option.
Chest-supported, cable, machine and barbell rows keep horizontal pulling in the session. An anchored band row offers another setup when weights or machines are unavailable.
Assisted dips keep the parallel-bar movement with counterweighted support. A seated machine dip offers a guided downward press; bench presses, push-ups and pushdowns fill broader pressing or elbow-extension slots.
Barbell, dumbbell and Smith machine bench presses keep a compound chest press with back support. Push-ups and an anchored band press offer other setups.
Bodyweight, front and back squats keep a two-leg squat. A dumbbell split squat can fill a broader leg-training slot when you want to work one side at a time.
Back, goblet and hack squats keep a two-leg squat with different load support. A leg press offers knee-and-hip extension with the torso supported.
Dumbbell split squats, reverse lunges and step ups offer other ways to train one leg at a time. A leg press is a broader supported, two-leg option.
Reverse lunges and walking lunges keep a stepping lunge. Dumbbell split squats and Bulgarian split squats offer a stationary stance instead.
Lying and standing leg curls preserve resisted knee flexion on a machine. Ball, suspension and Nordic curls offer other knee-flexion setups.
Dumbbell and machine hip thrusts preserve bench- or pad-supported hip extension. Floor-based glute bridges offer alternatives when the bench or barbell setup is unavailable.
Standing dumbbell calf raises, Smith machine calf raises and calf presses offer ankle plantarflexion when a seated calf machine is unavailable.
Standing dumbbell and Smith machine calf raises preserve heel raises with nearly straight knees. A seated calf raise changes to a bent-knee setup.
Barbell and Smith machine Romanian deadlifts preserve a loaded hip hinge. A cable pull-through offers a different resistance direction for the same broad hinge action.
A goblet squat adds a front-held weight to a two-leg squat. Reverse lunges and walking lunges offer unloaded split-stance work when a broader leg-training option fits your plan.
An incline push-up keeps bodyweight pressing with the hands raised. Dumbbell, machine and band chest presses provide other ways to keep a compound pressing slot.
An assisted chin-up keeps an underhand vertical pull with adjustable support. Pull-ups change the grip, and a lat pulldown offers a seated, externally loaded option.
A lat pulldown offers adjustable vertical pulling without an assistance pad. Assisted chin-ups change the grip, while band pulldowns and unassisted pull-ups use different resistance setups.
A seated face pull keeps the rope-to-face pull and rotation with a bench setup. Rear delt flyes, cable rear delt flyes and a reverse pec deck offer broader rear-shoulder options.
A cable rear delt fly or reverse pec deck keeps a wide-arm fly. Face pulls offer a broader rear-shoulder option that adds elbow movement and rotation.
Dumbbell flyes and cable crossovers preserve a wide chest-fly action. A machine chest press is a broader compound pressing option.
A dumbbell fly or machine chest fly keeps a wide-arm chest-fly action. A dumbbell bench press offers a broader compound pressing option.
A machine chest fly or cable crossover keeps a chest-fly action. A dumbbell bench press uses the same basic equipment for a broader compound press.
An overhead EZ-bar extension or anchored band extension keeps elbow extension with the arms raised. Lying extensions and pushdowns change the upper-arm position.
Barbell, EZ-bar and dumbbell curls keep standing elbow flexion without a cable station. A band curl provides another resistance setup.
A dead bug offers floor-based trunk control while the limbs move. A kneeling ab-wheel rollout adds moving support, while a side plank changes to resisting sideways bending.
Cable and machine crunches keep resisted trunk flexion. A reverse crunch curls the pelvis from the other end while keeping the upper body on the floor.
Hanging knee raises keep a suspended leg-raising action with a shorter lever. Lying leg raises remove the hang, and reverse or cable crunches offer broader trunk-flexion options.
