Do not do that.
Increased frequency is only beneficial when you already know what the fukk you're doing. If you have to 'perfect your form next time', you aren't ready for increased frequency.
Only reason Bulgarian Method/Squat Erryday works for folks is because they have form down pat and they can autoregulate. Noobs and early intermediates cannot, that's why they get injured tryna do that shyt.
If you a puppy stay your ass on the porch and let the big dogs eat in the streets.
And who the fukk told you to tuck your chin under when doing deadlifts?
Your whole neck and spine should be stacked and neutral; in your stance before initiating the pull they should be straight with no observable rounding. Tucking your chin past a certain point would actually pull your neck down disrupting that neutral position. What a terrible physical cue to be giving folks outchea.
This is why people need to find a gym buddy that knows what the fukk they're doing and learn off them, not no damn YT videos which aren't interactive.
