I have been doing Chad Waterbury TBT since this year and its now my 2nd time round and close to finishing. I can only train 3 times a week and TBT is ideal for me and I like the variable set & rep progression laid out for me so I don’t have to think about it. I am logging my entries on a spreadsheet and using formulae to work out what to lift to beat my last performance.
The set and rep progression is already laid out in the TBT profile from week 1 - 8. I am having problems determining the figure to beat each time I use a specific exercise.
Say over the 16 weeks I have used Exercise A 5 times where its been used in set/rep ranges of 3x15, 2x8, 3x12 etc. I measure volume as sets x reps x load.
So if I do one week of 3x15 x 10kg = 450
next week (or next time I use same exercise) I might be on a 2x8 rep range, so to beat my “last” performance I have to lift over 28kg which is something I cannot do.
The only thing I can think of is to put the rep range into buckets so that 3x15, 4x5, 2x8 are in the 15-20 bucket & 3x18, 3x15, 4x8 in 45-54 bucket etc. So I should be measuring performance gains of the same exercise based on similar parameters ?
I have searched the web for specific advice on this and its not clear. My s/sheet can retrieve history of my volume (set x reps x load) for each parameter set (sets x reps) so I would like to automate a predicted 2.5% increase correctly.
So if I change to another routine (eg. Waterbury method) I would still like to use any historic ‘volume’ of what I have lifted in TBT to measure or even start the new routine on.
Does anyone have any thoughts on this ?
