This program is for training twice per week. The training is conducted in private with one personal trainer.
The key to getting the best results are to train with intensity and consistency. This is more important than how many times per week you train.
Many people prefer to train twice per week. We make some adjustments to the training protocol if you train twice per week. We often split up the movements, so that one session is more lower body and the second session is more upper body. The second session often includes some extra exercises that are not included in the Minimal Effective Dose (MED) one session per week program.
Many clients will move from one session per week to two sessions a week and vice versa depending on individual availability / recovery / results. You are your own experiment and you can find out what works best for you.
