It’s hard to give a definite answer to a question like this, but most people will start to see improvements in a few weeks with just a few sessions per week. As long as you’re staying consistent and putting an honest effort in, you can expect to see good results. Remember that no matter how awesome the piece of equipment is, it’s only as good as the effort you put in. The products aren’t magic and can’t do the work for you, but they can certainly help target what you’re trying to achieve better.
