This my 2 cents about Lotus BJJ Club. This is the best place for NYC kids to train bjj as my 4 year old attending it. Plenty of toddler kids starting 3 years old and up. Kids sparring according to their age/weight/height so its pretty fair. Abundance of toddler girls is pretty surprising. Most of the bjj gyms are pretty much same in general terms but Lotus Club is willing to work with you according to your needs. Cant wait for new bigger and convenient location to open up!!! Highly recommend!
