Who this guide is for
- Anyone planning a home gym and wanting to avoid regrets
- People converting a basement or garage to a gym
- Owners frustrated by a stuffy or noisy existing gym
- Renovators briefing trades for a gym fit-out
Weak ventilation
A sweaty gym with no airflow turns stuffy and humid fast, and that moisture can linger in the room. Planning ventilation suited to an active space keeps it fresh and protects the finishes.
- Avoid a sealed room with no airflow
- Plan ventilation for heat and moisture
- Watch for humidity in basements especially
Inadequate impact flooring
Thin or hard flooring lets dropped weights damage the floor and the structure below, and makes training uncomfortable. Impact flooring suited to the equipment is essential, not optional.
- Avoid hard floors under heavy weights
- Match impact flooring to your equipment
- Protect the structure beneath from loads
Noise transfer through the house
Dropped weights and pounding cardio carry through floors and walls, disturbing the rest of the home. Considering how noise travels, and where the gym sits, avoids constant friction.
- Avoid placing a gym above quiet rooms
- Consider how impact noise travels
- Plan flooring and layout to soften noise
Underestimating equipment loads
Stacked weights and machines concentrate heavy loads, and not every floor is suited to them. A qualified professional should confirm the structure before heavy kit goes in.
- Avoid assuming any floor takes heavy loads
- Have loading checked by a professional
- Distribute heavy equipment thoughtfully
Poor lighting and mirrors
A dim gym is uninspiring and makes checking form hard. Bright, even lighting and well-placed mirrors keep the space energising and functional.
- Avoid dim, single-source lighting
- Add mirrors to check form and add light
- Keep the space bright and motivating
