What’s the difference between medium-range training and lsd training? 2. what are the benefits of the starter phase of a fitness program?

1. LSD (or long slow distance) training, also known as a continuous training,  involves performing an activity, such as jogging, cycling or swimming, nonstop for a period of time. This training is targeted for health-related improvements and is often required before engaging to more demanding, aerobic methods like fartlek. Medium-range on the other hand, is where the work period is dominated by the lactic acid energy system. This occurs either when the work period  is between 10 and 60 seconds or when the work-to-rest ratio is 1:2 or 1:3. The aim of medium-interval training is  to develop tolerance of lactic acid.

2. The starter phase allows the body to get used to the idea of exercise, avoid soreness and injury, and to experiment until you find the program that works best for you.
