Burn belly fat at home: This Décathlon device tones your core.

Spending hours sweating in the gym, paying for a pricey membership, then queuing for equipment - for many people, the very idea of a gym is enough to put them off. Yet the aim of a stronger, more defined body (especially around the stomach and core) doesn’t go away. That’s exactly why a compact piece of kit currently creating plenty of buzz at Decathlon has caught attention: the Power Tower CRIVIT, a small multi-station tower that turns a corner of your living room into a practical training space - with no dumbbells and no high-tech machines.

Home training instead of gym hassle

It’s a familiar pattern: you join full of enthusiasm in January, and by March you’ve barely been. The commute is a nuisance, opening hours don’t fit real life, and someone is always on the one bit of equipment you actually need. For lots of people, motivation isn’t the main barrier - logistics are.

That’s where bodyweight training at home shines. You use your own body mass as resistance, you don’t need much floor space, and you can start whenever you have a spare moment. The Power Tower CRIVIT sold via Decathlon is built around this approach. It’s a multi-part station that lets you perform pulling and pushing movements for your upper body and core, without loading a single weight plate.

The concept is simple: one piece of equipment that trains arms, back, chest and - crucially - your core, with no subscription, no travel, and fewer excuses.

Power Tower CRIVIT by Decathlon: what makes it different

At its heart, the station is a solid upright frame with multiple handles, pads and supports. It’s rated for a maximum user weight of 150 kg, which isn’t a given at this price point. That capacity can make a real difference to confidence and perceived safety, particularly for heavier or stronger trainees.

Key construction features include:

• Adjustable back pad - supports the lower back during core-focused work.
• Padded arm supports - ideal for knee raises and leg raises.
• Multiple grip options - narrow and wide grips for pull-ups and other pulling variations.
• Stable base - designed to keep the unit planted, even when sessions get more intense.

The tower comes with a fitting kit and a training booklet. That may sound basic, but it’s genuinely helpful if you’re new: rather than stitching together a routine from random videos, you get ready-made, structured ideas to start with.

One tower, multiple muscle groups

A major benefit of a tower station is that it reduces the need for several separate machines. Many classic gym movements can be replicated here - and sometimes made more challenging, because your own bodyweight forces you to control the whole movement.

Exercise	Primary muscle	Supporting areas
Pull-ups	Upper back, latissimus dorsi	Biceps, forearms, core tension
Dips	Triceps	Chest, front deltoids
Hanging leg raises	Lower and oblique abdominals	Hip flexors, grip strength
Supported knee raises	Rectus abdominis	Core stability, hips
Oblique variations	Obliques	Waist, lower back

For core training specifically, hanging leg raises (either free-hanging or using the arm supports) provide a strong stimulus. They often hit deeper stabilising layers that many people struggle to target with standard floor crunches.

Belly fat: why a tower can’t perform magic tricks

The manufacturer doesn’t promise miracles, but user feedback is still notably positive. On Decathlon’s platform, the unit sits at around 4.5 out of 5 stars. Buyers frequently highlight the sturdy feel, straightforward instructions, and the sense of having a “proper” home alternative to a commercial gym.

If you train consistently and align your diet with your goal, your waistline can change noticeably - the tower is the tool, but you supply the consistency.

It’s worth being blunt, though: no machine on earth burns fat only from your stomach. Fat loss happens across the body, not from one “target area”. What the station can do is:

• Build core musculature - more muscle mass typically raises resting energy expenditure.
• Work large muscle groups (back, chest, arms) - bigger movements usually mean higher calorie burn.
• Improve visible definition once overall body fat drops.

If you buy it expecting a “lose belly fat instantly” gadget, you’ll likely be disappointed. If you train 2–4 times per week and adjust your eating habits, there’s a realistic chance your waistband will feel looser over time.

A realistic training plan you can actually stick to

For working adults and parents, training windows can be short. That’s why a compact full-body approach fits well with a tower station. Here’s an example 30-minute beginner plan:

Day A - upper body & core focus

• 5–8 assisted pull-ups (using a stool or light jump to start), 3 sets
• 8–10 dips with foot assistance, 3 sets
• 10–12 supported knee raises for abs, 3 sets
• Floor plank, 3 × 30 seconds

Day B - core & technique focus

• 3–4 sets of negative pull-up holds (hold at the top, lower yourself slowly)
• Side knee raises on the arm supports, 8–10 reps per side, 3 sets
• Close support hold on the handles (tight support position), 3 × 10–12 reps

A practical weekly rhythm is Monday, Wednesday and Friday, alternating Day A and Day B. Over time, you can add volume, reduce assistance, or introduce external load - for example, a weighted vest.

Stability, size, and living-room practicality

A common complaint about home equipment is that it looks bulky and feels flimsy. Many Decathlon reviews say the opposite about this tower: phrases like “robust” and “stable” come up repeatedly. One user at 80 kg reports no wobble even with hard sessions.

Visually, a power tower is still a noticeable piece of gym kit in the room. If you live in a small flat, measure first to ensure you have enough ceiling height and floor space. The upside is that it’s far narrower than a full rack with a barbell bench setup, doesn’t require weight plates, and doesn’t need complicated storage.

Why bodyweight training is so effective for your core

A lot of “ab training” content revolves around quick floor routines and “six-pack in 30 days” challenges. In reality, a strong midsection is usually built through compound movements where your whole body has to stabilise under tension.

That’s exactly where a pull-up and dip station earns its keep. Even a strict pull-up demands core engagement because you must brace, stay long through the torso, and control any swing. With leg raises, you drive the legs against gravity while the hip flexors assist and the obliques keep the pelvis steady.

Train regularly on a station like this and you quickly realise your core isn’t just “working a bit” - it becomes the control centre of the entire movement.

The benefits go beyond appearance: a stronger core can reduce strain on the spine, support better posture and balance, and lower the likelihood of day-to-day back discomfort. For desk-based workers in particular, it’s helpful when the core does more than simply hold you in a chair.

Two extra factors: setup safety and progression

Before your first session, think about where the tower sits. A flat, even surface matters; if you’ve got hard flooring, placing a thin rubber mat underneath can help protect the floor and reduce minor shifting. It’s also sensible to keep the surrounding area clear so you can step off safely if your grip fails.

Progression is equally important. If pull-ups and dips feel out of reach at first, that’s normal - start with assisted versions, negatives, and shorter sets. As you get stronger, gradually reduce assistance, add reps, and improve control before you consider extra load. Good form and consistent practice will change your physique faster than rushing into advanced variations.

What to watch alongside the equipment

If your goal is to lose belly fat, focusing on one device alone isn’t enough. Several simple levers have an outsized impact on results:

• Nutrition: a modest calorie deficit, plenty of protein, fewer highly processed foods.
• Daily movement: more activity outside training - stairs instead of the lift, short trips on foot.
• Recovery: adequate sleep and rest days between harder sessions.
• Combination: two tower sessions plus one additional cardio session per week (for example running or cycling).

If you have health limitations - such as shoulder issues or significant excess bodyweight - speak to a GP or physiotherapist before starting. Overhead and hanging movements demand healthy joints and sound technique.

For everyone else, the Power Tower CRIVIT can be a straightforward entry point: once assembled, it’s there in your living space as a constant prompt - mildly guilt-inducing, but also motivating. And in practice, that daily visual reminder is often what gets you to do “just ten minutes” in the evening - the kind of small, repeatable sessions that can reshape your core definition over the long term.
