Notes

I am one of those people who function better by writing things down. One day, I realized that most of my notes don’t have to be private, so here they are - my second brain. Be warned that, if you stumble upon something here that doesn’t make sense to you, it isn’t meant to!

Deadlift form

Deadlift Step 1: Shin should be 1 inch away from bar. (So, middle of foot directly under bar. This is important.) Point toes out a little, not too much. (This will allow the knees to go out into the elbows later.) Barbell doesn’t go forward at all from this point on. Step 2 - grip: (Don’t use alternate grip because that creates asymmetry.) Leave ass up. You’ll want to roll the barbell but DON’T do that. Leave knees tight (i.e. wherever they are). Step 3: Bend knees until shin touches the bar. Hips don’t move after this position. (Hips higher than what you want.) Don’t drop the butt. Push knees a little into the elbow. Lift chest and drop belly between the knees. Step 4 - going up: Drag bar along the shins. Lift the chest up at the end. That’s the finish. Think of pushing the feet into the floor.

Dumbbell-only workouts

https://www.muscleandstrength.com/workouts/dumbbell-only-home-or-gym-fullbody-workout.html https://forum.bodybuilding.com/showthread.php?p=1266579671#post1266579671 - only 2 days a week, so maybe not enough volume. https://www.reddit.com/r/Fitness/comments/2e79y4/dumbbell_ppl_proposed_alternative_to_dumbbell/ https://www.muscleandstrength.com/workouts/frankoman-dumbbell-only-split.html - probably split the last section into two days. Splits across muscles - do once I have made some gains from some other programs. https://www.muscleandstrength.com/workouts/dumbbell-only-upper-lower-workout-routine - looks good. Maybe do after working full body for 3-4 months.
