Group Activity: A Comprehensive Guide
The ‘Group Activity’ category on Sidea brings together equipment designed for group exercise studios: aerobics, SuperPump, Fit Boxing, HIIT, circuit training, step classes, trampoline, kettlebell competitions and small pieces of equipment for fitness training. The products are selected to withstand cycles of intensive use, with several consecutive classes in a single day and dozens of different users handling them. You’ll find height-adjustable step platforms, modular tatami mats for combat fitness, freestanding punching bags, kettlebells ranging from 8 to 32 kg in standard IKMF/IKFF sizes, and SuperPump kits complete with a barbell and vinyl discs, elastics, fitness tubes and trampolines for rebounding.
What is Group Activity: definition and function
The term ‘Group Activity’ refers to the range of equipment designed for group classes held in a studio to music or under the guidance of an instructor. Unlike weight room equipment, these products prioritise ergonomics, lightness, stackability and speed of set-up: a step must be adjusted in 5 seconds, a SuperPump kit must be able to be assembled by the user before the class, and a tatami mat must slot together without tools.
The common thread is multiple use: the same piece of kit is handled by different people over the course of a few hours, so the materials, finishes and straps must be able to withstand sweat, controlled drops and minor everyday knocks. This approach also applies to the resistance bands and fitness tubes for progressive resistance training and the yoga and Pilates mats used in the Body & Mind classes.
Types of Group Activities
Aerobics steps and platforms
The step remains the iconic piece of equipment for group classes. The Sidea range includes entry-level models such as the 0231 Easy Aerobic Step, professional versions such as the 0235 Premium Step with heights of 10, 15 and 20 cm, the Mini Aerobic Step 0231/2 for bodyweight exercises and the 0230/1 with 16 steps for workouts of varying intensity. The SiStep 0212W is designed for studios with a more refined aesthetic.
SuperPump kits and barbells for toning classes
BodyPump-style classes require light barbells with vinyl or polyurethane discs fitted to screw-on collars. The 1129 PU (19.5 kg polyurethane) and 1133 vinyl (18 kg) sets are sized for the most common range found in Italian gyms. For individual work on the sumo squat deficit, there are dedicated sets with raised platforms.
Combat Fitness and Fit Boxing
For group boxing classes, you’ll need a punching bag, tatami mats and a stopwatch. The 2107 StrikeBack freestanding punching bag, the EVA mats in 2 cm and 4 cm thicknesses (9204, 9205, 9207, 9230, 9231) and the 0005 LED timer make up the basic set. For more information on flooring, see the relevant category tatami.
Small pieces of equipment for HIIT and circuit training
Kettlebell competition (2189V–2194V), 3603 fitness trampolines, 2050 and 2050V hammocks, 2090 Slidisk, 8030 Dune Ball Board, holistic cork kit and latex bands make up the stations in the rotation circuits. The idea is to have a wide variety of lightweight equipment for 30–45-second stations with quick changes.
How to choose: a guide to use cases
Commercial gyms with a dedicated training room
The priority is quantity: you’ll need at least 20–25 steps, the same number of SuperPump kits, a modular tatami set covering 40–60 square metres, and spare parts that will remain available over time. It is best to opt for the Premium range (0235, 0230/1), which is better suited to the 4–6 daily classes typical of a mid-sized centre’s schedule.
Personal training and small group training sessions
With classes of 6–12 people, the mix changes: fewer steps, more small pieces of equipment (trampolines, hammocks, Slidisk, latex bands, Dune balls). The 1×2 m 3025 mat is used for core and mobility work at the end of the session.
CrossFit and functional training studio
The gym doesn’t run aerobics classes in the strict sense, but it does use tatami mats, competition kettlebells for EMOM swing and snatch sessions, trampolines for conditioning, and sandbags during the winter months. The 2189V–2194V competition kettlebells have a consistent external diameter regardless of weight, a technical requirement for girevoy and the StrongFirst snatch test.
Advanced home gym
Those who train at home using formats inspired by group classes should opt for a SuperPump kit (1129 or 1133), 2–3 step machines, a 3603 trampoline and a 9205 basic tatami mat to protect the floor. Add kettlebell It rounds off a full-body workout.
Technical glossary
- SUPERPUMP
- A group toning class using a light barbell (15–20 kg) and vinyl or PU discs. The session focuses on high-rep squats, deadlifts, extensions and curls, performed in choreographed sets set to music.
- REBOUNDING
- Trampoline training based on controlled bounces. It reduces the impact on the joints compared to running and helps improve balance, cardiovascular fitness and proprioception.
- EVA TATAMI
- Interlocking puzzle-style EVA foam flooring, typically available in thicknesses of 2 cm (for recreational use) and 4 cm (for combat-fitness use). It absorbs the impact of falls and insulates the floor beneath.
- SNATCH TEST
- StrongFirst and Girevoy Sport standardised test: 100 kettlebell snatches in 5 minutes using the standard weight (24 kg for men, 16 kg for women). Requires a competition kettlebell with a fixed handle.
- DEFICIT
- A technique for performing squats or deadlifts in which the feet are positioned higher than the barbell, thereby increasing the range of motion. The 0231/2K and 0231/3K kits are designed for this exercise.
- EMOM
- Every Minute On the Minute: an interval protocol in which a new set of repetitions begins every minute. The 0005 LED timer with a configurable count is the standard piece of equipment used to manage this in the gym.
- FIT TUBE
- An elastic latex tube with rigid handles at each end, available in different resistance levels, each colour-coded. Used in aerobics, rehabilitation and small-group training for exercises involving variable resistance.
- DUNE BALL
- A balance board with a spherical or hemispherical base, used for proprioceptive and core exercises. It introduces controlled instability, which is useful for neuromuscular conditioning.

The 1129 kit uses polyurethane (PU) discs weighing a total of 19.5 kg, which are more resistant to scratches and falls and have a higher density. The 1133 kit features vinyl discs totalling 18 kg, which are less expensive and lighter to transport but have a shorter service life in intensive use scenarios. In commercial training centres with multiple daily sessions, the PU discs last significantly longer.
-
For Fit Boxing and martial arts involving controlled falls, 4 cm-thick tatami mats are used, such as the 9204 Red-Blue and 9231 Grey-Black models. The 2 cm mats (9205, 9207, 9230) are suitable for yoga, Pilates, gentle exercise and core training classes, where there are no significant impacts but an insulating, non-slip surface is required.
-
For group work involving swings, goblet squats and cleans, we recommend competition kettlebells (2189V-2194V), which maintain the same external dimensions from 8 to 32 kg. This allows participants who change weights during the session to maintain the same technique. For a class of 10–12 people, you will need at least three kettlebells per weight category from 12 to 24 kg.
-
The 3603 model is designed for use in exercise studios for rebounding and mini-trampoline cardio classes. It can withstand multiple daily sessions with users weighing up to approximately 100 kg. For classes involving very low joint impact — such as those for older adults or post-injury rehabilitation — it remains one of the most effective solutions in terms of the cardiovascular workout to joint stress ratio.
-
The number depends on the maximum capacity of the class. A typical setup involves 20–25 steps for studios accommodating 25–30 participants, with a few spare units for maintenance rotation. It is best to opt for a single model (0235 Premium or 0230) to ensure consistent heights during group choreography.
-
The Premium 0235 features a more robust frame, a dedicated non-slip surface and height adjustment with reinforced supports to withstand repeated loads during SuperPump barbell toning classes performed on the step. The Aerobic Step 0230 is the standard model, suitable for classic aerobics classes without significant additional loads.
-
The 2107 StrikeBack is a freestanding punching bag with a weightable base, so it does not need to be fixed to the ceiling or wall. This feature makes it suitable for multi-purpose training halls, where equipment needs to be moved between classes. Once the base is filled with sand or water, it ensures stability for medium- to high-intensity Fit Boxing workouts.
-
Yes, the 0005 timer allows you to programme customisable work and recovery intervals, suitable for Tabata protocols (20 seconds’ work / 10 seconds’ recovery for 8 rounds), EMOM and HIIT. The LED display ensures visibility throughout the exercise room, which is important when the class is following the round count without looking at their smartphones.
-
The 0409 in TPE (Thermoplastic Elastomer) is a fold-out mat that folds like an accordion; it’s practical for transport but has a stiffer structure than a classic yoga mat. It is suitable for Pilates, mobility exercises and post-class stretching. For regular yoga practice, the 1x2 m 3025 mat offers more surface area and better cushioning for floor-based poses.
-
A basic setup for groups of 6–8 people includes: 8 Mini or Easy step platforms, 6–8 mats, a set of latex bands and fit tubes in various resistance levels, an LED timer, 2–3 fitness trampolines, a 2 cm EVA mat to mark out the soft zone, competition kettlebells ranging from 8 to 20 kg, and small proprioceptive equipment such as dune balls and slidisks.
