Upper body superset! Not only does adding more movements into your sets cut training time in half (aka more time for exploring when you're travelling) but it can work to establish a more positive hormonal response! How? Utilizing minimized rest periods will inevitably increase the acidity of your blood (due to increased lactic acid/blood lactate levels). This increase in acidity will trigger the release of growth hormone! Basically, by maximizing the amount of growth hormone you produce, you can decrease body fat and improve muscular hypertrophy resulting in an overall better body composition!
