Frequently asked questions
Cast iron or vinyl kettlebell?
Cast iron is more durable and professional. It handles impacts better and lasts years. Vinyl protects your floor and costs less, but wears out faster. For calisthenics, go with cast iron if you want a long-term investment.
How many kettlebell weights do I need?
Depends on your level. As a beginner, one kettlebell is enough (8-12 kg for women, 12-16 kg for men). At intermediate level, get 2 different weights to vary exercises. Advanced: an adjustable kettlebell saves space and money.
What weight to start with?
Women: start with 8-12 kg, progress to 12-16 kg. Men: start with 12-16 kg, aim for 16-20 kg after 2-3 months of regular training. If you struggle with 20 clean squats, take the lighter weight.
Are adjustable kettlebells as effective as fixed ones?
Yes, if the locking system is solid. Adjustable kettlebells like Eric Flag's let you progress without buying 5 different bells. The only downside: slightly bulkier than fixed ones. For home calisthenics, it's the best compromise.
Can I do calisthenics with only a kettlebell?
No, the kettlebell complements your practice, it doesn't replace it. It adds explosiveness and leg work that pure calisthenics often lacks. Combine it with push-ups, pull-ups and dips for a complete program.
