Always follow what works best for you. You are the best judge of what works for you. My journey is perfect for me. Your journey is perfect for you. YOU ARE PERFECT.
A few things that might help you achieve your goals...
Be consistent.
Start a progress log so you can make simple entries to show and record what you've tried. That way you can see what works and review modifications you've made. It will also serve as an accountability vehicle for yourself and and encouragement to others here in the forums.
That's a good routine starting out for the first few weeks or month. However, you will need increase your workout time and intensity for meaningful growth.
Try in the coming week to add an additional day to your workout schedule. Try a 2 on the 1 off schedule. Or 2 and 2. Aim for a 3 and 1 off or 3 and 2 schedule over the next month or so.
