If you are a coach, we encourage you to purchase the full, long form Learn to tackle course as this provides a much deeper dive into the what and why of tackle training, in addition to providing guidelines on structuring training for all periods of the year: off-season, pre-season, in-season.
Players are directed to the shorter form programs as these are much more to the point spell out exactly what should be done in training, and only cover the periods of the year where tackle training is athlete led and performed in small groups (off-season and extras. The pre-season and in-season period should be primarily team based and coach led).
