Trained legs today. Felt much better physically today. Slept for 8.5 hours instead of my usual 5.5 hours. Beginning to wonder if training to failure all the time is good for the spirit and body? What did Lee Haney say? Stimulate don't annihilate. Bill Pearl said the same in his own way.
One thing here.
You trained legs 3 days in a row.
You did deadlifts and hypers on 4/1, Deads hit the quads, hamstrings and lower back. Then 4/2 you ran and hit the bag which also uses the legs. Today 4/3 you trained legs.
Over-training, my brother. No recovery time. No healing time. The symptoms you describe are classic over-training effects.
How about taking a day off between training? Rest, recovery, healing. No weights, no running, no nothing. Rest.
Read a book, watch a movie, get a hobby, whatever. No training.
If you want to split your workout do push/pull/legs or push/pull-legs. Day off between training. No running on off days.
Full body do everything but only 1-2 exercises per bodypart. Running can be scheduled on training days or as a separate training day.
No matter what take a day off between training. Complete rest.
