Hey forum, I'm new here and also new to weight lifting. I am about to start the second week of 10s and I have some questions: Metabolic work during the 5s? - Have heard that this can be added to improve growth in some lagging areas, but in the eBook it says it isn't recommended to beginners because "those who are early in their training need to focus on building the foundation". What does this mean? I was planning on adding some lateral raises, some form of chest work (cable crossover or squeeze press) and maybe some tricep work. Currently my routine is: Incline DB press Cable row Dips Chins Arnold press/ overhead DB press Leg extensions Leg curls Cable crunches All of this 3x a week MWF I think this is a pretty solid set of exercises considering my gym has no barbell and dumbells up to 30kg. Large loss of chin up strength? - So up until now my chin up progression has been entirely using the assisted chin up machine. Besides the last day of 15s, the chin ups should have been a walk in the park for me (pre SD I could do 12 BW before failure so I took my 15 rep max as the lowest increment on the machine, -5kg) however I have been having great difficulty reaching the designated reps for the first set from about -12kg ish on the machine, let alone the second set if I planned on 2 sets. I have had to start clustering my chin ups in this last week. None of my other lifts have been affected this much by my SD. My weight didn't change during SD either. However, I never actually tried the assisted chin ups pre SD, so it could be significantly different to unassisted chins, which could be why I found them so difficult. Tomorrow is my first day doing unassisted chins so I will have to report back. I am away for several separate weeks this summer - what kind of useful work can I fit in 2 weeks training - 1 week away - 3 weeks training - 1 week away - 2 weeks training - 1 week away? Is it at all possible to fit in some kind of HST cycle here? Thanks for responses.
