I specified "hiking on a trail" because I think walking in the woods is harder than walking on pavement and this trail had lots of ups and downs.
Strength- arms, abs, legs.
New pregnancy workout schedule for now:
Tuesday- Strength (including pilates or yoga)
Thursday- Strength (including pilates or yoga)
I will probably switch the running to exercise bike or swimming toward the end of the pregnancy when I get ridiculously big or it starts hurting.
