Just finished fundamentals course and purchased FOUNDATIONS and (3 part) STRETCH SERIES. Very excited about progressing, but stuck before starting when setting up online schedule. I'm a soccer player (age 37) and play once a week, but play at an intensity that my legs are shot for at least 2 or 3 days after. I dont understand the layout/intensity of the GST programs and am wondering what is the ideal layout/schedule so as not to set me up for an injury (had several muscle/tendon tears and strains from training/playing while still sore)
