Semi-private sessions are based on what we call holistic training.  Holistic training is strength training that considers each individual client and optimizes their health by improving their speed, power, strength, mobility, balance, stability, and aerobic fitness.  During a 60-minute Semi-Private session, we focus on whole-body strength and conditioning.  Every six weeks the program changes for variety of movement and so that clients can upgrade their repertoire and skill set. Training is tailored based on each client’s experience and skills, so even beginners can participate.  

The safety of our clients is of utmost importance to us, so we make sure that each client performs every exercise with proper technique.  We don’t progress clients until they have “earned the right” to progress, meaning that they have demonstrated confidence, high skill and have completed the required criteria for moving up in weight or difficulty.  We aim to improve by 1% or more each session, so our clients develop confidence and a sense of achievement when they realize how much they are improving.  Via this wise approach to progressing over time, our clients start experiencing greater health, strength, mobility, performance, and a higher quality of life in as little as three to six months. 

To properly care for each client, our Semi-Private sessions are limited to 3-5 clients.  The session length is 60-minutes. 

Semi-private sessions are perfect for those who want to improve their strength in a holistic way and enjoy training with others.  Pricing starts from 26,400 yen per month for 4 sessions.

Session Flow (The following program is an example)

Our Warmups have 2 parts:

Part 1 – Movement Warm up as a Team

This is a simple mobility warm up that takes about five minutes to complete.  We warm up the entire body from head to toe preparing the joints, muscles, tendons and ligaments.  We also connect with each other through light conversation and sometimes share some highlights of our week.

Part 2 – Deep Stretching, Power Movements, Balance, and Speed-Coordination Drills

We work on these in a circuit which lasts about 4 minutes. 

Station 1: Medicine Ball Slam (Upper Body Power)
Station 2: Rope walk (Balance and Coordination)
Station 3: Hanging (Upper Body Deep Stretching) 
Station 4: Jump catch (Whole Body Power)

The Main Sets

Incorporating strength training and core training in a well-balanced manner, we carry out exercises that suit each client’s level.

We train the whole body.

Station 1: Kettlebell Deadlift (Target muscles – the entire back side of the body, core and grip)
Station 2: Push up (Target muscles – Chest, front deltoids, triceps and core)
Station 3: Side plank (Target muscles – the core and especially the obliques)
Station 4: Seated Cable Row (Target muscles – the upper back, rear deltoids, biceps and grip)

We run two main sets to cover all the functional movements of the body, the second main set will generally target muscles such as shoulders, hamstrings, core, arms and upper and lower back.    


Here is a sample of our Cardio Strength Training:

Station 1: Battle Ropes (Upper Body and Core focused)
Station 2: Duck Unders (Lower Body and Coordination focused)
Station 3: Military Push Ups (Upper Body and Core focused)
Station 4: Jump Rope (Calf & Quadriceps and Coordination focused)

This is what we consider a very well-balanced, holistic training session that has our clients reaching their health, fitness, fat-loss and muscle-gaining goals.
