This is the problem I have with your single limb lifts for a sprinter:
In the spp, with intensification taking place in the the target events I often find it necessary, among other adjustments to drop single limb lifts, to allow for greater recovery and to keep the performances moving forward. Again I think it’s a risk/reward situation and I find them more draining to the overall training load and not providing any significant advantages. I’ll keep the other lifts such as back squats, rdls, hyper complex etc in the program.
If you must add single limb lifts to your program I think gpp would be the perfect time for this type of work.
