We have been using the day time kids Sports Classes. Marc has been amazing with my 3 boys. He has a calming nature but can match the kids energy matched with good banta. This is such a good find in islington and would highly recommend it. The staff are friendly and professional.

They run several sports sessions for kids from ages 2-4 and 4-7. The coaches are excellent, really good at engaging with kids and ensuring they make the most of their sessions. The sessions are very easy to book and the staff is quite flexible to accommodate last minute bookings. The venue is a bit small, but big enough for the classes and drills required for kids at that age They’ve got an excellent cafe on site serving high quality, and healthy food and drinks.

I attended a few beginner boxing classes and Dan is a great instructor. The class size is small, which allows him to check everyone’s combinations and correct them. He is very patient, which motivates me to try harder. I look forward to continue more classes.

I attended Hollow Rocks 148 basketball classes in 6 months from March to September this year. All the staffs and people who join the sessions are some of the most genuine people I’ve ever met. Give Hollow Rocks a try, you wont regret it!

I attended my first beginners boxing class, it was great fun, very friendly staff. Dan the boxing coach was friendly and gave lots of helpful pointers! I ended up being very early so sat in the cafe, a great vibe, lovely fresh orange juice. Chatted with staff on the cafe, all round a great experience and I'll be back!
