@dollfaceme23 Negatives are super effective. They will work. If they are really hard just rest enough in between the reps. 40 every other day will be a crazy volume. Be prepared to get really sore.
If you can't fit 40 in your day start with 20. And increase the volume when you get stronger.
@dollfaceme23 Hi I assume you are a female from the stats.
Good thing is you are short and light so it won't be so hard after you got your first reps.
Here is how you do it: Drop the bands. Just do negatives. Jump to the bar or use a chair. And then slowly lower yourself. Try to make it last...
