What is the Deficit Sumo Squat Kit 0231/3K?

The Deficit Sumo Squat Kit 0231/3K is a complete solution for deficit leg training. It includes a T-Bell Handle 9011, 2 Mini Aerobic Steps 0231/2 and 4 steps 0231/1. The kit enables you to perform sumo squats and straddle lifts with the load positioned below the line of your feet, maximising the activation of the glutes and adductors during deep squats.

Which muscles does the deficit sumo squat target?

The deficit sumo squat emphasises the activation of the gluteus maximus and the adductor muscles. Standing with your feet wider than shoulder-width apart, with your toes turned outwards, reduces hip flexion compared to a standard squat and promotes a greater focus on abduction and adduction. Lowering the weight below the line of your feet increases the stretch and activation of the glutes.

What does the 0231/3K kit contain?

The kit includes: 1 T-Bell Handle 9011 for a natural grip on the weight, 2 Mini Aerobic Steps 0231/2 to serve as a footrest, and 2 pairs of step risers 0231/1 to adjust the height of the steps. The T-Bell weights are not included and must be purchased separately.

How do you use the T-Bell Handle in a sumo squat?

The T-Bell Handle 9011 allows you to grip the weight with a central T-grip, whilst keeping the weight naturally centred and pointing downwards. This configuration enables you to lower yourself into a full squat without the weight touching the floor, as your feet are raised on the Mini Steps. The central grip promotes the upright torso posture typical of the sumo squat.

Can the heights of the steps be adjusted?

Yes, the kit includes 2 pairs of 0231/1 steps, each 5 cm high. You can add further pairs of 0231/1 steps by purchasing them separately to increase the height of the steps further and adjust the gap between the steps and the footrest.

Who is the Deficit Sumo Squat Kit suitable for?

This kit is ideal for those who want to train their legs and glutes, with a specific focus on the gluteus maximus and the adductors. It is suitable for powerlifters, bodybuilders, athletes and strength training enthusiasts looking for a solution to perform sumo squats and straddle lifts to maximum depth with added weight, whether in a professional gym or at home.

What exercises can you do with the 0231/3K kit?

The kit is designed for sumo deficit squats and straddle lifts. The sumo deficit squat is performed with the legs spread wider than shoulder-width apart, feet on raised steps and the T-Bell held between the legs. The straddle lift is a variation of the deadlift performed with the legs spread apart. Both exercises utilise the deficit to increase the range of motion.

Is the 0231/3K kit compatible with other Sidea steppers?

Yes, the kit includes the Mini Aerobic Step 0231/2 and the 0231/1 steps, which are part of the Sidea step range. You can combine it with other models such as the Easy Aerobic Step 0231, Aerobic Step 0230 or Premium Step 0235, or add further pairs of 0231/1 steps to customise the height and configuration to suit your training requirements.

Deficit Sumo Squat Kit - Practical kit specially designed for training the legs, particularly the buttocks, by performing squat exercises with deficit overload in relation to the standing surface of the feet.

The kit takes its name from the famous squat variation known as the Sumo, due to the split-legged posture reminiscent of sumotors. The Sumo Squat is characterised by a very wide leg opening, well beyond shoulder width, with the toes of the feet naturally over-shouldered.

This results in less hip flexion and extension, typical of the standard squat, in favour of more abduction and adduction work. Consequently, on a muscular level, we have a greater activation of the adductor muscles and the great gluteus.

Gluteus whose activation and stretching will be greater the greater the depth of the squat. In order to achieve a full, maximally deep squat using an overload, in order to further stimulate the muscles, the technically simplest solution is to hold a weight in a natural way, with the load weighing downwards.

The T-Bell 9011 represents, from this point of view, the simplest and safest solution, to be combined with the Mini Steps 0231/2 in order to be able to descend with the load itself below the foot support line.

For these reasons, the T-Bell Deficit Sumo Squat Kit 0231/3K is a practical solution for training the legs, particularly the buttocks, by performing exercises in maximum squat, with overload, and in deficit with respect to the footplate; Deficit Sumo Squat and Straddle Lifts.

Additional 0231/1 step pairs can be added to the kit to further raise the steps: step pairs 0231/1
