I was so impressed by my session with Bill at HardCore. I work out regularly and know my way…read morearound a gym so didn't think HardCore would be that different than a regular studio training session. Boy was I wrong! HardCore was a really creative, effective way to change it all up. Think TRX completely, brilliantly redesigned and expanded upon by physiology geniuses. As Bill led me through a full body workout I was engaging so many muscles in new, smart ways with the proprietary equipment. And as tough as this workout was, it was very low impact, felt utterly safe, and I felt no stress on joints the way regular weight lifting can do. Even though I wish I could do weekly sessions to incorporate HardCore into my fitness routines, I am so glad I tried this while visiting and will definitely go back when I visit again.

The locker rooms are a nice layout and with 4 showers, there is typically 1 available. The layout of the workout equipment made sense and it was good amount based on the number of people so it was also available. I requested wanting to do an hour on the stairmaster and the adjustment to make this possible was done within a day. I liked using the hot tub for recovery after my workout but when it was closed, you literally had to go right up to the pool area to know that; there could have been a sign by the front desk, a sign entering the locker room, etc. but there was just a sign on the door AFTER completely going through the locker room where realistically one had already changed.

On top of that they charged us $100 extra after paying over $700 for our treatments because our daughter was with us and used the pool area while we were getting our treatments. We tried to get one for her but they were booked. The young gal at the front desk didn't need to be so rude as there could have been an attempt to ask for an exception this one time. It's sad that basic common sense has been depleted in today's world that even w customer service employee behaves in such a manner to a paying, returning customer. One hundred dollars today cost this place much more in the long run. Hire better. The guys at the pool bar by the way, were absolutely fantastic!

I get my exercise in hiking and biking during the summer, but needed to find a way to get a good sweat now that I've retired from skiing (if you can call what I did skiing). I was excited to see they had a treadmill/circuit training type of class called the mill. I did the power mill class 4 times during my week in Sun Valley and loved it so much. All 3 instructors I took with (Sophie, Maggie and Josie) were challenging and energetic. It was a good combo of running and weight lifting - I hated it during the workout, but felt so good when I left. Sophie's class was probably the most challenging of the 3 and she was also super friendly and welcoming to a newbie like me. Her Sunday morning class was also the smallest with only 3 of us so spent a lot of time correcting our form as well. I think you can't go wrong with any of the classes here and if you love to run they have a run mill class that's all on the tread. Excited I found this amazing workout for my frequent trips to Sun Valley. It seems popular among the locals, but tourists should try it too. And the first class was only $15 on mind body!
