After a weeks rest, I felt good first session back I did legs.
Day 1 and 2 after it hurts when I sit on the toilet, I struggle to get back up. I'm on my hands and knees going up stairs if there isn't a handrail and I'm walking around like I've got a sweet stuck up my arse...love a good leg sesh
I'm in the same boat right now. Killed legs on Monday after a week and a half off, only I didn't go all fancy, just did a solid 7 sets of squats. It's mid week now and it still hurts getting up off the couch.
To speak before you think is like wiping your ass before you shit!
IMO leg extensions have their place, however I don't recommend a lot of weight but high reps with low weight to cut and give good definition. Every time I go heavy with leg extensions, the next day my knees ache and can barely walk. When I go high reps I feel fine and muscles feel nice and tight.
Never accept anything less than the best for yourself
