I'm Jeremy Shore for LIVESTRONG.COM, and this is how to body build in your thirties. There aren't any major differences in how you train between your twenties and thirties. However, Nick Tumminello, owner of Performance University, does think there are a few things to consider. First, don't try to lift too heavy, which can cause you to cheat and diminish the benefits of your body building workout. If muscle growth and maintenance is your goal, slow it down and focus more on form and intensity by increasing the time under tension. Next, you may need to consider your posture. After years of sitting or performing dysfunctional repetitive movements, you'll need to spend more time on your posterior chain. Targeting the muscles of the mid-back, glutes and hamstrings. Perform more exercises like wide grip barbell rows and seated rows for the back. Hip bridges, Romanian deadlifts, and squats for the legs. Finally, recovery between exercises and between workouts may take longer during in thirties. Allow yourself longer periods of rest and don't be afraid to take a couple of days off, a week, to allow your body to properly regenerate and recover.
