@Achieve234 : What does your
pulling schedule look like? How often (sets and reps) do you do Pull-ups, Rows, and TFLRs? Do you do any other pulling exercise (like simple Tuck Front Lever holds)?
Actually I'll have to disagree slightly. There are various reasons (I can go into them if you want me to) why a Straight-Arm exercise like the Front Lever is harder with straight arms. In fact, a common compensation is to bend the arms somewhat. So while a straight-arm Planche is a particularly difficult feat (one I'm still far from), a bent-arm Planche is actually quite easy (and have been able to do for many years).
It's so much easier with bent arms, that 5 Planche Push-ups (which might take 10 secs to do) can actually be easier than a 10 second Planche hold. It can go either way. Same logic for the Front Lever.
Calisthenics progressions are ordered based on difficulty. That's why it's called Progressive Calisthenics. I know it sounds like a good idea that you'd need a full Front Lever before ever doing Tucked Rows, but the reality is that OP is clearly capable of the Tucked FL Row and almost definitely nowhere close to the full FL. That will decide the ordering for OP. For people like
@pet' capable of a FL, the TFLR is a joke of an exercise and useless for him at this point. It is like thinking that you need to squat 500 lbs before ever trying to DL 300.
Through years of experience, the calisthenics community has found that FL Row work is usually about
one progression behind the FL holds. So those capable of a good Adv. Tuck FL hold, can probably get some good TFLR reps to be a productive exercise.
If you care to know, Planche PU work usually lags about
one and a half progressions behind Planche holds. Meaning, it wasn't until I could do One-leg Tuck PL for a few seconds that I could finally tackle Tuck PL PUs with productive form.
