I am after some advise but I think the answer might simply be rest!
At the end of '18 I followed the plans (SSB and onwards) at mid-volume. Since the beginning of the year I have switched to doing the time crunch 45 Monday - Friday due to new family commitments!
I have just been cycling the time crunch 45 plan since but recently I am finding my legs shattered by Thursday each week and struggling through the last two work outs. The part I find strange is I had been used to doing higher weekly TSS, is this simply a case of these workouts being more intense and I just need to insert a rest week?
Also does anyone else follow this plan and have you seen improvements using it?
