Is this better than sitting on the couch whole day? Yeah probably better. But strength is not size and esthetics. It's force production against an external resistance. big does not equal strong.
Calisthenics are definitely hard to program, but you can build a huge amount of body strength without weights. “Overcoming Gravity” is a great book if you’re ever looking to program body weight movements. This isn’t a knock on lifting weights, weight training is great and everyone should do it. It’s just that strength is in relation to something else, and that something else is what dictates what sort of practice you should be programming. Building an extreme amount of strength doesn’t need to include a weight if you’re clever about it.
There is an argument around calisthenics having too many compound movements and gaps in difficulty progression, which makes it hard to overcome specific bottlenecks. But what calisthenics absolutely is great at is mobility and CNS engagement. Combine calisthenics with a yoga mat and doorframe bar with bands training to add more granular progression and isolations, and you have some really good overall coverage with minimum equipment.
NB: One major reason we have historically seen more material about weights than bands is that it's easier to compare weight progression apples-to-apples. Bands change difficulty with slight changes in grip position, hence results are harder to compare.
I can't imagine what my fellow strength trainers are doing.
Also waiting. Lots of waiting. Hopefully I'll get my rack, barbell and weights this month.
