Five21 is a group training gym on the Pieter Goedkoopweg in Haarlem. The motto: you never train alone. The offer is broad, with functional training, HYROX, weightlifting, BJJ and grappling, (kick)boxing and personal training. For powerlifters, the Strength Class is the main draw.
That Strength Class is a twelve-week programme around the squat, bench press and deadlift. You build up the weight steadily, with plenty of attention to technique. The pace is slower than in functional training. After a while you work semi-independently on your own programme. The block ends with an informal mock meet, where you try to set a new record on the big lifts together. A new programme starts every twelve weeks, but you can also join halfway.
Prefer to do your own thing? In the open gym you train without a coach, with free weights, squat racks, plyo boxes and cardio equipment. Open gym is included in all memberships. If you're new, Five21 recommends doing a few Strength Classes first.
The gym is open on weekdays from 7.00 to 12.00 and from 17.00 to 21.00, at weekends from 9.00 to 13.00. You can book a free trial class.
