We recently asked 36,000 ACE-certified Fitness Professionals to name their single most important exercise items.

Some answers were obvious (my body), while others were more abstract (daily goals, plenty of space).

Here are their top 12 exercise essentials:

1. Good shoes
2. Fun or appropriate music
3. Free weights
4. A positive attitude
5. Comfortable clothing
6. Lots of water
7. A supportive sports bra
8. Safe, well-made equipment (e.g., cardio machines, heart-rate monitors
9. Weight-training gloves
10. Enough time
11. A workout partner
12. Fresh, clean air and/or sunshine
