+1 for gmb.io - it's the only program(s) that i ever paid for - they are that clever. (i am athletic, walk my dog daily, have access to crossfit gyms etc). gmb.io "fills the gaps" of daily movement deficits and is for everyone.
But when I go to the gym once per week, and do 10 different exercises with weights or machines, I want to know what weight I used last time so I can start there (or just above it) again. Maybe you have the memory of an elephant.
Or Maybe you don’t care if you spend 2 minutes at every machine first figuring out what weight feels like just enough, not too much or too little, before doing 3 sets? Enjoy that. But I don’t want to do that. Every. Single. Time i go to the gym. And there’s no way to see my progress?
I have not tried gmb.io, but looks like progression in that program involves moving onto more difficult movements rather than increasing weight.
I speak this as someone who has terrible memory.
Also contrary to another poster who insists on not tracking your lifts, I find it essential both for making progress and maintaining interest, its somewhat comparable to levelling an RPG character. At the very least its useful for remembering what you've done recently so you know what to do next.
