Class/Studio Review: F.L.E.X! takes place in the lower level of Studio Three and is high intensity interval training (HIIT) working at it’s finest. F.L.E.X! (the signature HIIT workout of Studio Three) is described as a “systematic approach to multi-planar, dynamic movement.” The sequenced intervals blend functional warm-ups, loaded explosive patterns with active rest and full recoveries. The class is a designed to rev up your heart rate then bring it back down (w/ an active recovery) in order to shock your body into change. The result is increased athletic performance, higher-quality movement and a raised metabolic rate that maximizes fat burning potential.
When you sign up for F.LE.X! you’re given a spot (number) that corresponds to a treadmill and subsequent spots at each interval (i.e., spot 4 @ treadmill, spot 14 @ interval 2 and spot 24 @ interval 3). During each interval you will follow the instructor’s cues to work through a sequence of movements including sprints/hills on the treadmill section. There are 3 rounds at each interval station (practice, perfect and push) where you will repeat the entire sequence until you have reached your maximum. Following each interval you recover with an active stretch movement.
Instructor Review: Instruction for Saturday morning’s F.L.E.X! class was led by Jenn Hogg (personal trainer, co-founder @ H.E.R.O. fitness and lululemon ambassader) and Wes S. (trainer and instructor). The two led and motivated the class through each interval. Interval 1 consisted of treadmill runs, interval 2 was a set of 3 exercises using TRX bands and interval 3 was lunges and lifts using a weighted sandbag. Each section was designed to exhaust you by the end. Just when I thought class was over, Jenn announced a group bonus round (3 minutes long) where we squatted and burpeed to the finish.
Would I Recommend? Yes. I would recommend adding F.L.E.X! to any workout regimen. I definitely enjoyed most of the workout and found it to be exhausting. My muscles felt worked and sore the next day. However, I felt the TRX section could have been a little more challenging, either by adding another exercise or quickening the pace.
