Been doing squats, leg adductors and abductors with bands, lunges, squat leaps, quad and hams.
It's definitely getting better. I can barely feel any problems with the groin. By tomorrow it should be fine.
Nevertheless... I don't need a setback so I'll try and keep all sprints under 75%, concentrating on 400s - bright and early tomorrow.
One good thing is that my weight remains very good at 137.8 which is surprising since I've been eating a lot of fat in the form of nuts lately and I've gone back to putting raw sugar in my tea.
