Each person has their personal preferences and thresholds, so it’s difficult to recommend a definitive intensity. Select an intensity that works for you. It should be comfortable but challenging enough to leave you feeling like you’ve had a hard workout. You can increase this over your six-week plan.
Naturally, each muscle group across your body will react differently to certain intensities (your legs, for example, may have a higher intensity threshold than your arms). We recommend making notes of your intensity preferences and comfort levels, so that you can monitor your progress and start every toning session where you left off.
