CrossFit® Twenty Pound Hammer: Opinions

5/5 (5 Opinions)
Amanda Snyder 3 years ago

Fantastic experience: I've been attending this gym for almost a year, and it's been an amazing experience! All of the coaches are extremely welcoming, friendly and knowledgeable. If you are like me and found yourself wandering around the gym weight room and not pushing yourself in your workouts, I highly recommend you try a class at Twenty Pound Hammer. It's been nothing but rewarding for me physically and emotionally. I would also add: don't to be intimidated. Everyone is always learning something new and in different places with their skills and fitness level. The coaches do a great job at meeting you at your skill level by scaling workouts so they're doable, while also teaching you new things and pushing you to do your best. In short, it's a wonderful community and I highly recommend this gym!

Fantastic experience: TLDR: Female-led, amazing coaches, intelligent and safe programming, wonderful community vibes, generous trial plans. 5/5, would recommend to anyone, regardless of skill/fitness level and or familiarity with Crossfit. Full review: I have been a member at TPH for over a year now (joined Jan 2021,) and I still frequently get emotional regarding what an impact this gym and its coaches have had on my well-being. I cannot say enough or too many good things about Twenty Pound Hammer. I have a history of various eating disorders, body dysmorphia, and exercise addiction, so I was weary of starting Crossfit, given its generic reputation for being anywhere from culty and overly intense to downright unsafe. TPH IS NONE OF THOSE THINGS. Twenty Pound Hammer has allowed me to feel strong and excited about getting stronger. I come from a 20+ year background in dance and have a group fitness certification myself, so my standards and expectations for coaches/instructors is high. The coaches at TPH exceed them *daily.* They are so so smart, so safe, so kind, and so in tune with the people in the room at any given time. They always lead the group through a thorough and relevant warm up, welcome questions, offer lots of scaling options, share helpful tips and tricks, and in general are just amazing. I firmly believe this is the best Crossfit gym in Seattle. Give the gym a try for a week or a month; they have trial plans to see if TPH is a good fit for you! (This ad was not paid or sponsored…I just love them this much.)

Fantastic experience: I can not recommend this gym and its coaches highly enough. The programming is smart and fun, as are every single one of the coaches, and community as a whole. Definitely a special type of Crossfit gym worth checking out.

Fantastic experience: This gym is the best in Seattle. Period. If you join any other gym other than Twenty Pound Hammer, you are wasting your time and money. The two lead coaches, Melissa and Monica, are the best athletic coaches/trainers I have ever experienced. They are incredibly knowledgeable, motivating, and welcoming. They have built a radiating sense of community within this gym as well. This place and its coaches are the best part of my day. If you want to grow physically, mentally, and personally, join this gym. The coaches genuinely care about every aspect.

Fantastic experience: I've been a member for six months and I am now attending classes five days a week (from two days a week) and I feel great! Super supportive community to workout with. The coaches are on point and help everyone achieve good form and set high standards. I have a manual labor based job and have incurred injuries while at work; the coaches are able to scale any movement or lift to my personal needs. I love this gym.
